The room was small and it was a small mattress. However, the flat is clean and you have anything you need to stay. The flat is very central, close to a lot of underground stations. A supermarket is next to the flat. If you like biking, you can rent a bike at the Santander docking stations close to the flat. Yolanda was pretty nice and she was there at the arrival and at the leaving. I definitely recommand the room!!
