Roberto is an awesome host. First the communication was great, everything i needed to know was shared with me and he was always available to answer my questions even by Airbnb chat since i was always outside to visit the city.
The location os great, really near the metro station and easy to find.
In terms of confort and privacy i can say that you can fully rest and you won't feel that you are staying in someone else house.
I think it's a great option if you are visiting Madrid.
