Jose Isaías Medina-Argueta pleaded guilty to harboring illegal aliens and conspiring to harbor illegal aliens in violation of 8 U.S.C. § 1324 and 18 U.S.C. § 2, but reserved the right to contest the district *481 court’s “vulnerable victim” enhancement under the United States Sentencing Guidelines § 3Al.l(b)(l). He claims that the district court erred by increasing his guideline sentence range two levels pursuant to the vulnerable victim sentence enhancement. We agree that the district court erred in applying the vulnerable victim sentence enhancement, but conclude that because Medina-Argueta’s sentence falls within a properly calculated guideline range, his sentence is presumptively reasonable.
I
Medina-Argueta’s presentence report recommended four enhancements: a six-level enhancement because the offense involved between 25 and 99 illegal aliens, a four-level enhancement because Medina-Argueta brandished a pistol during the offense, a two-level enhancement because Medina-Argueta intentionally or recklessly created a substantial risk of harm to the aliens, and another two-level enhancement because Medina-Argueta knew or should have known that at least one illegal alien was a vulnerable victim. Medina-Argueta was entitled to a three-level reduction in his offense level for acceptance of responsibility. His criminal history score was zero, and combined with his total offense level of 23, this resulted in a guideline imprisonment range of 46 to 57 months.
Medina-Argueta objected to the presen-tence report recommendation, arguing that the evidence did not support a finding that at least one alien was a vulnerable victim. After hearing testimony, the district court overruled Medina-Argueta’s objection. The district court found that there was at least one vulnerable victim involved, possibly more. The court also granted the Government’s motion for a downward departure for substantial assistance, which resulted in a guideline range of 37 to 46 months imprisonment. On March 23, 2005, the court sentenced Medina-Argueta to concurrent 37 month terms of imprisonment, concurrent three-year terms of supervised release, and a $200 special assessment. Medina-Argueta filed a timely notice of appeal challenging the district court’s ruling on the vulnerable victim two-level sentence enhancement.

After
United States v. Booker,
*482 A
Section 3Al.l(b)(l) of the United States Sentencing Guidelines provides for a two-level enhancement “[i]f the defendant knew or should have known that a victim of the offense was a vulnerable victim.” Comment 2 of that section explains that a vulnerable victim is someone “who is unusually vulnerable due to age, physical or mental condition, or who is otherwise particularly susceptible to the criminal conduct.” This court has determined that, in order for an illegally smuggled alien involved in a violation of 8 U.S.C. § 1324
1
to be a vulnerable victim, he must be
“more unusually vulnerable
to being held captive than would be any other smuggled alien.”
United States v. Angeles-Mendoza,
Because an alien’s illegal status is a prerequisite to the crime of alien smuggling, it is error for a district court to find unusual vulnerability based on that status.
Dock,
In Medina-Argueta’s case, the district court stated:
I look on [aliens] as desperate people who are reaching out .... No one died here and there is no evidence of any injury. I cannot attribute that to the fact that these people were treated humanely and with dignity, however. I think a lot of the fact that they remained alive could be due in no small happenstance to good fortune. I consider placing them in a small, the report says, 15-by-15 room, as extremely inhumane. I consider holding people against their will until money is obtained extremely inhumane. I do think there was vulnerable victims here, at least one, possibly more, and I so find.
Medina-Argueta contends that the district court erred in applying the vulnerable victim enhancement. The Government claims that the district court did not err because the aliens were confined in an apartment that measured only 15-by-15 feet, the temperature in the apartment was uncomfortably hot, one alien was held for two weeks while the smugglers waited to be paid, and the aliens were from Honduras and had therefore experienced more prolonged stress than aliens smuggled from Mexico. Two possible errors exist: (1) the above factors are conditions of smuggling, not personal characteristics of an unusually vulnerable victim, and (2) the district court did not substantiate its conclusion that one or more victims was vulnerable with specific findings or by direct observation of the victims.
Although it is unclear whether the district court intended the smuggling conditions to substantiate its vulnerable victim finding, none of the factors to which the Government points are characteristics of a victim that would tend to place him in the same category as the young, old, or sick, rendering him particularly vulnerable for purposes of the sentence enhancement. In
United States v. Angeles-Mendoza,
we found that the district court committed clear error in finding vulnerable victims when 29 illegal aliens were held at an Austin stash house. The smuggled aliens
*483
were held until the defendants received fees for the transport; to deter escape, the defendants took the aliens’ shoes and socks, and guarded them in a boarded-up and locked stash house with a shotgun.
The guidelines represent Congress’s determination, through the Sentencing Commission, of how much punishment a particular crime deserves, taking into account the inherent nature of the type of offense .... Although the court may have been correct in noting the inherent vulnerability of smuggled aliens, we assume that such a characteristic was adequately taken into account in establishing the base offense level.
Id. at 747-48.
Along with possibly relying on the conditions of smuggling, which are not directly relevant to the vulnerable victim determination, the district court also failed to substantiate its findings with personal characteristics of the victims. Like in
Angeles-Mendoza,
the district court in the instant case “failed to mention a characteristic [of a victim that] the defendant knowingly took advantage of, such that the offense demonstrated the extra measure of criminal depravity which § 3A1.1 intends to more severely punish.”
Angeles-Mendoza,
B
Due to the enhancement error, the district court miscalculated the appropriate guideline range and sentenced Medina-Argueta after considering an incorrect range. Under
Duhon,
a miscalculation of the guideline range “deprives the sentence of ‘great deference’ and is a factor to be considered in assessing the reasonableness of the sentence.”
In our cases reviewing sentences imposed after
Booker,
we have not had occasion to address the applicability of
Alonzo’s
reasonableness presumption when the district court initially miscalculates the guideline range. We hold that in situations such as this, in which the district court miscalculates the guideline range yet imposes a sentence that falls within a properly calculated guideline range, the sentence enjoys a presumption of reasonableness. This conclusion comports with our prior decisions.
See Alonzo,
*484
We do not believe that
Angeles-Mendoza
counsels a different outcome than the one we reach here. In
Angeles-Mendoza,
the district court incorrectly applied the same § 3Al.l(b)(l) enhancement as was misapplied here, and this court remanded for resentencing in light of the guideline miscalculation.
III
Though the district court miscalculated the applicable guideline range, Medina-Argueta’s sentence falls “within a properly calculated guideline range,”
Alonzo,
Notes
. This statute provides criminal penalties for bringing into the United States or harboring certain aliens.
. Furthermore, the district court stated that, in its view, any lower sentence would be inappropriate. In contrast to the facts of
Angeles-Mendoza,
Medina-Argueta’s sentence was not imposed
"as a result
of an incorrect . application of” § 3A1.1(b)(1), which would require reversal under the still-intact 18 U.S.C. § 3742(0(1).
