My girlfriend and I spent 9 nights in this accommodation and we consider our stay as more than convincing.
The room perfectly corresponds to the description and the pictures of the ad. The room, such as the whole accommodation, were perfectly clean and we were offered several times during our stay to have the room cleaned and the sheets and towels changed.
The bed was very comfortable and the bathroom functional. The parking spot is part of the good points too. We also had access to the wifi from our room, which was very handy.
The biggest minus point is the fact, that guests aren't allowed to use the kitchen, which was quite disconcerting for us due to the strict diet I have to follow. Breakfast was provided and served to us by a lovely girl named Valentina. However, breakfast was quite minimalist and the strict minimal.
A ventilator was provided in the room and we cannot complain about it. But if you want to reach the top, a room with air conditioned would make the nights perfect!
My overall opinion is positive and I would consider coming back to this accommodation if I happen to come back to Pisa.
