My family and I (2 adults, 1 child) recently stayed at Mario’s listing and was a fantastic first experience for us with AirBNB. The apartment is private, well appointed, and in a can’t beat location right in the heart of Plaza Mayor within walking distance to many restaurants, attractions, and easy access to transportation (taxi, metro, etc). Both Mario and Noelia were kind and welcoming hosts – even placing an order for some food for us one night – and were very quick to respond with whatever inquiry we had about the area, apartment, etc. We’d highly recommend this apartment and would definitely book again if/when we get back to Madrid!
