Beatriz and her family were outstanding hosts, providing prompt and professional support; in one case we locked ourselves out of the apartment and Beatriz responded promptly to get us back into our unit - it was later in the evening requiring some driving time for her!
The apartment is very well maintained and Beatriz communicated periodically to make sure we were comfortable; all of our requests were promptly met.
We really liked the location, we walked to 'Retiro Park' and the museums (my wife and I love to walk!); there is also a wonderful park 10-15 minutes walking distance from the apartment with a great view of greater Madrid from the hill top, complete with snack and Beer bar - it is intended for the Vallecas neighborhood we assume, we just stumbled on it.
In summation, in our view, this apartment provides excellent value: a great comfortable bed and shower with an excellent location; the fact that the hostess and her family are some of the nicest people we have encountered during our many extended travels is simply a bonus!
Enjoy!
