The flat itself is really nice and the location is great to explore the city. Very central and you can easily walk to all highlights. It is not the cheapest option and what we disliked was the enforcement to take a certain taxi when arriving late from the airport. Communication was great and we received replies very quickly to solve problems and questions. The only thing when we arrived late was the floor was quite dirty and the bed linen was dirty with some spots on them which was not so comfortable but we told them and it was cleaned the next day and extra linen was under the bed. Still, unfortunately, it leaves a negative memory although the apartment is great and Madrid a wonderful city to explore from here.
