Our stay here was really nice, everything was just the way described on the AirB&B profile. The place is located in the city center, super close to Puerta del Sol so you can visit all most important places in Madrid just by walking. Despite such location the building is very quiet, we didn't experience any noise. The room doesn't have a window (as described) but it has a fan so it wasn't too hot inside. The washrooms were clean, we didn't have any problems with waiting to use them. We highly recommend coming here! Perfect for short trips :)
