The management company for this apartment is very good at communicating and being available for any doubts, very nice and attentive people.
The apartment is located in the very center of Madrid, it is easy to go by walking to many of the tourist areas, but it is extremely noisy, and constantly crowded. There are lots of police and ambulance sirens every day and night.
The apartment itself is cozy. The room size is perfect for two people. However, the doors (building doors and apartment door) are a problem. The locks are tricky and quite difficult to open. If you are coming back from a long night out, it may get very upsetting. The trash disposal in the area is also a nightmare.
One of the chairs in the living room area looked quite dirty. And there was not hand-soup in the shower. But overall, all necessities were covered, with extra towels and bed sheets.
Overall, the place is ok for a few nights in Madrid. My biggest problems were the noisy area and the doors lock.
