The apartment looks exactly like the pictures. We found it a bit small but it had everything we needed. We weren't much in the apartment so the size wasn't too much of an issue for us. The location is perfect, is close to everything!... The only bad thing is that the apartment is on the 5th floor and there isn't an elevator in the building but other than that I would recommend it to anyone going to Madrid.
Rut was very nice and welcoming and we were able to leave our bags with her before check in and after check out.
