Mario couldn't be there when we arrived but he had his friend waiting for us. She was great, explained how to use appliances, where everything was located, and answered all our questions. He contacted us several times to be sure all was well, he also printed our boarding passes, We had an early departure, he was there to accompany us to a taxi to make sure we got away on time and correctly. He was there start to finish! The apartment is very nicely appointed, with nice quality items, he has taken care of every detail. It is also in an amazing location within walking distance or metro stop of all the major sights in Madrid. We were also very pleased with how quiet the apartment was, no noise from the plaza. We would highly recommend this apartment. Mario is a very attentive host. Thank you so much.
