This was my second time in Raul's house and as he says all the time 'mi casa es tu casa' I can only confirm that it's true and that I felt home.
Raul is a great host, always in for a chat (and help if you need some) but you also have all the privacy you want. Even if the bed isn't very comfortable for me (back problems) after a few nights I would defenitly stay again next time I'm in Madrid.
Raul and Konstantin see you next time!
