The loft is very clean, comfortable and definitely corresponds to the descriptions and photos, if not overcomes them. The place is also very well located in Madrid. It has a very good shower, kitchen and laundry machine.
Rutilio, the owner, was very precise to the schedule of check-in and also provided us some good instructions on how to locate ourselves, where to eat etc.
The only negative observations I'd have about our stay is in relation to the owners saying that they couldn't help us at all to leave our baggages in some safe place before check-in and after check out, which is very common for hosts to do and seemed that they had the meanings for that. Also, they gave us only one key to the apartment, and we were in 3 persons, including a old lady. So if we wanted to arrive in different periods we had to arrange some meeting time or to walk all the three floors stairs to open the doors to each other, once the outside door can't be opened from the loft.
