I live in Madrid. Spending this NY'eve in an other flat, just me, to get inspired, was not a classical "AirBnB" situation I would say.
Giorgio's place is THE place for that kind of "quest". It is full of humanism.
Now for those who expect classical feedbacks, I highly recommend it, since it gathers all what it is needed to have a nice stay in Madrid (center).
I will go back, definitely.
