This apartment is well located, especially if you like to visit Madrid's museums. The Prado, the Thyssen-Bornemisza and the Reine Sofia museum are all at about 10 minutes walking distance and all very much worth a visit. To the other side the Plaza Mayor and the main shopping district are also within walking distance. In the streets around the apartment you will find plenty of restaurants, cafe's and little shops.
The apartment itself is perfect for 2 people spending a few days in Madrid. It is light, nicely furnished and very clean. Both its owner and the concierge were very helpful and check-in was smooth.
We would happily return next time we are in Madrid.
