This was a fantastic option. I was only in Madrid for a couple of days and this apartment was in a perfect location within walking distance to the main tourist spots and the metro station. Also the place itself was just as described with everything you could possibly need, clean, neat, and very nicely decorated.
Antonio was also a very nice host. Very prompt getting back to me if I had any question and he was there to welcome me upon arrival. I would stay here again anytime.
