The apartment was great, exactly as descibed in the anouncemnt. Pictures are perfect too. It is ideal for 5 people (we were 3, anyway). It is really closed to 2 metro stations (5' walking) and just around the corner there's a very good supermarket. Pilar was great: she was waiting for us at home and she provided maps + lists of things to do and see (and how to get to those places).
It is a bit hot but using the fans provided (there's one in each room) we had no problems at all.
Also, it was a bit noisy outside but if you close the windows it is not a problem anymore.
