It was the first time I was using airbnb and it turned to be a great experience. Marga is very serviceable and willing to help at any time. The room had a queen size bed, a reasonable wardrobe to comfortably fit clothes for 1 week, and a decent desk for a laptop. Also the rest of the flat is nice, with good wifi connection, and the house was always clean. Marga's place will be the first I check the next time I go to Madrid
