We had a very nice stay, everything was super clean. The appartment is very nice, lovely furnished and very close to the centre and metro station. You can even walk to Atocha station in 10 minutes. There is a big market and supermarket just across the street to buy groceries. Nice restaurants and cafés are close by. Only thing I would like to mention is that I would not recommend to stay with five people in the appartment as the sleeping couch is a little bit small.
