The apartment (which is in a residential/hotel complex) was a little dark, the air conditioning is a little noisy and it's missing a table to be able to eat properly at lunch or dinner. Great position though, super close to the center (literally 10 mins away on foot to Puerta del Sol passing by Sibeles), very clean and the host is very dependable (we were missing the hair dryer and they delivered one to us through the reception in no time!) . I'd book it again!
