We are a couple and stayed in the apartment for 6 days.
The place lived up to the photos, a bit small (and dark tiled)bathroom maybe but quite good standard.
The size is perfect for a couple.
Its location is very good in the central barri and it lies near to the metro stop of San Martin.
Although the stay had for us a huge catch since the kitchen was not fully functional. The second day we wanted to make dinner but couldn't get the stove to work. We contacted the host and were told that we needed a remote that she claimed there were 3 of laying around in the apartment. We told her we couldn't find it and after 2(!)days she admitted she thought we were a couple from an other apartment and thought we talked about the AC. She told us that she would be in the area the next day (our 4th of 6) and could come over to explain us how we might could get it to work. But she never called. We rented the place with fully equipped kitchen so that we could have the privilege to make dinner at home, so of course bad communication our impression is quiet negative as the stay didn't fulfill to our expectations.
On another hand Alicia was thankfully flexible about meeting us at the door on arrival.
