You could not wish for a better location! You can walk everywhere by foot, no matter which monument or popular place you wanna see in Madrid. Moreover, check-in and check-out times are very flexible, which is especially great if you have heavy luggage. Also, coming home in the middle of the night wasn't any problem. Francesco was really helpful and had already prepared a map with his personal recommendations of restaurants and places to visit. Towels, bedding, and shampoos were provided. Just be aware that you will only be happy with this bedroom + bathroom if you don't mind very tiny rooms and old buildings. The mattress wa pretty comfortable, though, and everything was very clean. All in all a clear recommendation!
