You could not wish for a better place to stay in Madrid! We were already impressed by its pictures and the reality was just great. Very very very central, yet very quiet, very stylish and comfortable and very well equipped with a full kitchen, a wash machine, etc.
Taller people would have to be careful in the lower parts of the apartment, but for us it was amazing as in a fairytale.
You should be quick in the shower before warm water turns cold. And don't forget to close roof windows in rainy days. This also soundproofs the apartment for the night, making it a great place to rest after walking for the entire day in wonderful Madrid.
Jose was a very caring host, who gave us great tips and helped with storage of our luggage after check-out.
Very recommended!
