We stayed a week in Rocío's place. The neighbourhood is very cool and lively, loads of restaurants and bars that are worth visiting.
Future guests should know that this is not a place for those sensitive for sleeping. It is on the third floor on a street with loads of traffic. While we were there there was a construction project next door (and it seems like everywhere in Palermo). Saturday there was a party in the building and we heard it all night long.
We had problems with the check-in due to a tricky front door.
Rocío and Ana were very accommodating and helpful.
