Javier's apartment is in a great location to access all of Madrid's sights by foot or by metro. The station and 2 metro stops are 5 minute walks away. The Prado is 650 m and the other 2 galleries closer, so handy for free openings times.
The apartment is new and very quiet. Everything as it should be.
We had a great time and thoroughly enjoyed Madrid. Javier was available 24/7 tho we never needed to call. There is a Lidl 2.5 blocks away.
