We had a great weekend in Madrid at Ian and Alberto's place. The flat is ideally situated within walking distance of the bars and restaurants of the old town. As other reviewers have mentioned the flat although small is a perfect configuration for two couples travelling together. We were particularly pleased to find it quiet at night and the beds comfortable. It was also handy to have shampoo, soap etc provided and coffee at the end of a long day sightseeing. There was a bit of a mix up with the time of our arrival but this was soon sorted out. This was our first time using Airbnb and based on this experience it won't be our last.
