We have liked this apartment for its location: near Atocha railway station, main museums and parks, with some good restaurants around. The apartment is spacious and nice but obviously has not been renovated for many years and has not been cleaned before our arrival.
Please note that the apartment doesn't have any shower and washing accessories, so It's better to prepare a small set of them if your stay not very long.
Photos are good but they don't represent falling curtains and almost broken chairs...
