I was apprehensive about staying in Retiro at first but the place is really nice and the area felt safe! There are some really nice areas nearby but none of the main hotspots (Palermo, San telmo, recoleta) are that walkable so bare that in mind! This being said, the building is very nice, gym does the job and the pool is long enough for some swimming! We also had someone come into clean midway through the stay which was a nice touch!
