The location of the apartment is convenient, very close to Gran Via and all of the major attractions. But, that also meant very noisy and crowded streets. The apartment building houses many units and is quite loud, especially on weekend nights. The listing mentions the number of stairs, there were many. It is technically the 4th floor (for US folks). Just be prepared if you have a lot of luggage. It was very clean and had everything we needed. The living area is small but plenty of room for sleeping 7 comfortably. Andres was very responsive and helpful. The listing says Family Friendly, I'm not sure it would be the easiest and most comfortable for very small children given the stairs and noisiness. Our youngest was almost 5 and he managed well.
