We loved the flat. It is compact, but has been well designed to make excellent use of the space available, much better than many of the flats we have stayed in before. We used the Airbnb app to communicate with Juan Alfonso and it worked brilliantly. We strongly recommend visiting his chocolate cafe. The location is on a street with many on-trend bars, within easy walk of many restaurants and museums. We only used the metro once in the 6 days we were there. We did a day trip to Toledo using the tourist train from Atocha, definitely recommended.
