We stayed in Ramon's apartment for 3 nights, and we absolutely loved the place. spacious and clean, super comfy beds, and the location is fantastic. Just off a busy street with lots of shops and places to eat, it was so quiet in the building and area, no noise what so ever. If I ever come back to Madrid, I will DEFINITELY stay here again.
(I can agree with the slightly odd smell in the ensuite bathroom though; bit strange. But there's another one, so it was absolutely fine)
