My wife and I traveled over the holidays to Madrid with our 1.5 year old and my father in law and stayed at the Madrid Rental Flats for 2 weeks. Even though our flight was delayed and late getting in on Christmas Eve, and I was having connectivity issues with my phone, Javier was right on time to meet us and help us check in. He was very welcoming and helpful in making recommendations for places to eat and for getting around.
The apartment was clean, spacious, and modern. It is super conveniently located. It is near the city center, but far enough out so that it is quiet. We enjoyed walking almost everywhere we went from the apartment and there are metro stops close by as well.
We enjoyed having a small kitchen to prepare a few meals during our stay and our son enjoyed stepping out on the cozy patio. We had all the comforts of home and enjoyed our stay.
