I only stay at Cristians place for one night, however I enjoyed to talk to him as he is very friendly and kind. I booked the room only a couple hours in advance and he accepted very fast. Furthermore he was fine with me to check-in around 10 pm which I really appreciated. The room was just as expected as in the pictures. Great was also that you could take the express bus from the airport to Atocha station which is like 5 min from his place. Would stay there again!
