A nice place to stay in Madrid. The apartment was tidy and convenient. All the facilities were available. There are a lot of nice bars and restaurants around the corner. Additionally, a lot of sightseeing is in a walking distance.
However, even if the area around was quiet at night, I can't say so about the house itself. For some reason, the walls block little noise. If your neighbors watch TV or talk through the night, you will hear every word. So, be prepared and better bring ear plugs.
