Jose's apartment is in a wonderful neighborhood. It's close to the livelier parts of Chueca but a bit more subdued. As others have mentioned, there are a few bars on the street, attracting enthusiastic crowds whom we saw on Saturday evening when we came home at 2:00am. With the windows closed we heard nothing, but this could be an issue for light sleepers in warmer weather with open windows.
We usually stay in La Latina/Lavapies when we visit Madrid. We love that area, but it was great to stay just a little bit further from the crowds of plaza mayor and plaza del sol, yet still be an easy walk from everything.
The apartment itself is very well-equipped. The wardrobe in the bedroom allowed us to completely unpack for the week which helped us feel at home. The washing machine and drying rack allowed us to pack light, which made carrying a suitcase up 3 flights no big deal. We would happily stay here again.
