My wife and I stayed at Fernando’s apartment in January 2019 with our almost one year old baby. Fernando went above and beyond to make sure we were able to check in. For instance, our flight landed late in the evening and he personally checked us in despite the late hour. He also went out of his way to make arrangements to return a bag we left behind, even though we had already checked out the day before and were only returning to town for a short period of time.
The apartment also went beyond our expectations - it’s very well designed and roomy, and in a great location. Check out the flea market on Sunday morning, which starts right below the building (though the apartment itself is very quiet). Would definitely stay again next time we are in Madrid!
