The apartment has a perfect location right in the heart of Madrid, walking distance to many important spots. It's quite well equipped, the only downside is that there's a lot of noise from outside in the night but I suppose it is perfectly normal due to the location and obviously same applies to any apartment right in front of a nice pedestrian area full of restaurants. Some things could be renewed like the floor and maybe some details in the bathrooms but not really important. If it's important to you to stay right in the center, go for it, it is quite comfortable!
