I had a wonderful stay at Ruben's apartment. The neighborhood is lively, safe and walkable to most major tourist attractions as well as many bars/restaurants/coffeeshops. On Sunday, El Rastro market was literally around the corner. The apartment itself was modern, spotless, and very comfortable. I stayed alone but could have easily Brought a guest. Ruben was a lovely host who was available for any questions I had about the apartment or about Madrid, he even recommended a couple of restaurants that I loved. I would definetly stay here again.
