I was Antonio's guest for more than a month and my stay was perfect.
Antonio was a great host, he was nice and polite, very attentive to my needs.
I particularly liked the view from the room. The shared kitchen has everything you need to prepare your meals.
Location is unbeatable. It's in one of the best neighborhoods of Madrid, very well connected to the main metro lines, with lots of good restaurants and cafes. The Chamberi Market is right around the corner.
Totally recommended for short and long stays.
