We had a great stay with David and would recommend his apartment to fellow travelers. David is very social and welcoming. He was also helpful with providing us pointers about how to get around town and things to see. Though you share the apartment with David, you still feel very much like you have the whole thing to yourself. David is incredibly polite and allows you privacy. We actually only saw him for maybe 30minutes the whole time we were there. Also, the bed in the guest room is amazing! It is sooo comfortable. Turn on the fan, open up the window, and you will get some of the best sleep, especially being his apartment building is super quiet, even though it is centrally located within Madrid.
