The hospitality was the best I have experienced with Airbnb. Charo greeted me when I checked in and woke up to say goodbye when I left early in the morning. She had good advice for how to get places and we had nice conversations each night. The photos do not do justice to the Airbnb: it is a beautiful apartment in a very convenient location in Madrid. Away from all the tourist spots (so very peaceful) but close enough to get to with ease, and close to the universities.
