Nice apartment in a good location where you can walk to all the main attractions. Lots of bars nearby, with many Indian restaurants at your doorstep, as well as African fusion nearby.
Javier communicated well but was not available to meet us and we were shown around the apartment by Freddie. The apartment was very clean and provided us with all we needed for a comfortable stay. The supermarket was not far to get supplies.
We visited the Prado and Reina Sofia museums which we really enjoyed. A visit to the Palace, the cathedral and Retiro park is also a must. Book online for the palace to avoid queuing.
Would definitely recommend visiting Madrid and staying at this apartment.
