Our family of 7 loved our stay at this place. It was clean, spacious and had everything we needed. The location was also absolutely perfect -- it is a quick walk to the Royal Palace of Madrid, Mercado de San Miguel, Plaza Mayor, Puerta del Sol, etc. It was very easy to communicate (through WhatsApp) with the person managing the Airbnb. They sent someone to check us in and show us around the place. They also helped us book a taxi from and back to the airport. Highly recommend this place especially to large groups!
