We really enjoyed staying in the apartment of Mariano and Janine! The communication was really good and it was possible to do the check-in earlier than indicated, which was perfect, because we arrived early in the morning. Furthermore the apartment was clean and had everything we needed. The metrostation is only a 10-minute walk away and there are many supermarkets close by. We also liked that the check-out is flexible, because you can leave your things in the apartment to discover the city until you have to go to the airport.
We will definitly stay here again if we plan to visit Madrid one more time!
