This was my first time using Airbnb so I was sceptical, but I loved it and will never go back to hotels! The space is perfect for a solo traveler, though it could work for a couple as well. The location was PERFECT. Right in the heart of the city, literally steps away from everything, including the hop-on-hop-off Madrid tour bus! Hosts were really responsive and helpful, and the place is basically brand new, spotless and well organized. It was a great experience.
