We had a really nice stay in Renan's Apartment. The apartment was clean and there was a nice bottle of red wine for the first evening. We had problems with finding out how the shower worked, but after a call with renan there was someone who could explain it in 2 seconds. Don't twist the lower knob, but tilt it and the shower works.. Nice neighborhood with fancy cafes/restaurants, but be aware of the noise on Friday (and probably saterday) night! If you blend in the crowd you won't have a problem with that. We would really go there another time when visiting Madrid.
