Overall, it's a nice place to stay in Madrid for a short/medium period. The geographical location is really good, 2 minutes down the street and you're in the center of the city with access to one of the main subway stations. However, it is located in a very bar/disco bar/restaurant intensive street and it can get loud sometimes at night (until 5am). If you have some trouble sleeping with noise this location might not be great for you, we were able to live with it. The apartment could use some maintenance and care as some things were in bad shape, close to breaking or didn't work properly. The cleaning of the apartment upon arrival was ok, the floor was a bit dirty.
Despite all this, we can recommend this apartment as you get great location and the basic stuff you need at home. Good value
