A lovely apartment in a fantastic location! Really in the middle of it all in a great area (5 mins from El Rastro market on a Sunday) and located near to lots of tapas bars and restaurants. We found for most areas in the city the apartment was no more than a 30 minute walk which was ideal and very close to metro station also.
The apartment itself has a well equipped kitchen and living room with a very comfortable sofa! The building was quiet and even outside considering the central location we didn't have much noise.
I would stay here again and would recommend to friends looking for an apartment in Madrid!
