I've stayed at Ayres de Recoleta twice in the past 2 months and found this place to be very pleasent and above all, is perfectly located for all the clubs in Recoleta.
During both my stays, the A / C was working fine. The only problem I encountered was during my first trip, when internet connectivity was unstable.
More importantly, I never encountered any trouble in bringing girls back. I brought a total of 5 girls back during my stays and not once was I asked for the girl's ID and checked if I was ok after the girls left. The only reaction I ever got was the hotel staff gazing jealously at my 'take-aways'.
I personally have no problems in recommending this place.
