I stayed in Diana's apartment for five days with my boyfriend and we were really pleased!
Alvar, her son, who was waiting for us to show us the apartment, was very friendly and made us feel welcomed.
The apartment really had a beautiful view and great light and everything was clean and tidy. Kitchen had everything we needed, yet we only had breakfast at the apartment (right next to the apartment there is a lovely bakery where we could buy medialunas) and the bath was great, hot water!
Besides all, the neighborhood is nice and it was not hard to get to the places we wanted to go: walking a few blocks in one direction there is the metro station, and in the other direction, Palermo and bus to the city centre.
The only thing we could say is that, if you have trouble sleeping, the bed can be a little bit hard.
Having said all that, I can highly recommend Diana's place!! The apartment is super and we were very happy with it! It really was a cozy place to rest after walking the whole day in Buenos Aires !
