Our hosts were the most delightful and helpful people you could hope for, and were gracious to a fault. We could not even convince them to be OUR guest for dinner on the last night of our visit. In addition, two cats inhabiting their flat added so much pleasure to our stay! (They don't have to be present, but we preferred the company and they were terrific to have around.) The flat is near everything and we were able to walk most places comfortably. Once we took the Metro after a long day of touring, and it was only a few stops from the city center. By all means, follow Jorge's recommendations on food, wine stores, shopping, dining -- all were good tips indeed. About the flat itself, some comments: We were very comfortable but I wished for one cushy upholstered chair to sink into, so the hammock ended up as my choice for a relaxation spot. The top floor location offered enough ventilation that we turned on the AC one time and then didn't really need it. Everything is homey and well-furnished that we felt "at home" even in a strange foreign city. We wished the elevator was running but that was the only real negative so we didn't complain at all. OK, the only other negative was a neighbor (across the street and one floor down) singing "karaoke" -- badly -- until midnight one time. The occasional street noise was actually entertaining. That point is subjective -- I would imagine there is NO place in Madrid that is perfectly quiet, and if there is then it must be so boring that no one enjoys their visit!
