Very clean. The room is quite small and dark (only a small window overlooking a courtyard where very noisy people live LOL)
Nice position, close to shops and cafes. Perfect for a walk at night too.
Unfortunately we stayed during the coronavirus lock down so we had to spend all our time in the room eating canned food (no microwave or kitchen in the room/building). Hopefully we will be back one day to enjoy the beauty of Madrid.
