Our needs are pretty basic. Provide a quiet, comfortable place to recharge after a long day of exploring at a reasonable rate. Buenos Aires is amazing and you need to visit and explore the gorgeous city, wonderful people, amazing food and rich history. BUT I would advise anyone to LOOK ELSEWHERE for a place to stay!
Beds are comfortable, but place is outdated and worn. Importantly, a LOUD, big, vocal dog lives in the next building directly beneath the windows of the master bedroom (which has inadequate windows that have space on either end allowing noise to penetrate the master bedroom). The dog begins his barking early in the morning and seemingly goes until late at night. It is LOUD!!
The exterior walls do nothing to shield the noise. Photos make the place look really nice, but we were fooled! Air conditioner drips into the room when it is set too low, but the setting is required because the building has extremely thin windows and the apartment has insufficient window coverings. When we arrived, the inside of the unit was at least 80 degrees F. It took several hours to cool the place to where we could sleep comfortably. In addition, some (not all) towels provided had fresh makeup smudge marks on them and some were full of holes and tattered. They were replaced the day after we arrived.
Although it is marketed as though the owner is a local woman named "Claudia", who can provide local knowledge and passion for travelers, I dealt with a guy in Minnesota. We never saw or heard from "Claudia".
Good luck!
