I can say that all that we are looking for in apartment were realized in this case. Excellent apartment located in the most central that possible. The apartment is equipped with all required and the apartment is fully protected. The connection with Celma and Gert was excellent, they were waiting for us in the apartment (even it was in late at night) and guided us about the apartment and surrounding area. Celma and Gret help with all our needed and was very pleasant company. No doubt, in our next visit in Madrid, we have place to be back.
