Location: great, safe location, close to the metro, cafes, and other needs you might have.
Check-in/out: the process for checking in is strict. 3PM was our check in time. We arrived early and Francesco provided a location of a place where you can store baggage. As for the check-out, we had to drop the keys to a different location and turned out to be really hard to find. The name of the place he mentioned was not the one it turned out to be and took us a long time to figure out the correct place.
Communication: Francesco was very communicative with us when we had to contact him.
The place: It was note completely clean and found the place not entirely cleaned, even someone else socks left behind. There was no extra toilet paper and had to get our own but Francesco was nice enough to refund us for having to run out to get some. Also keep in mind that the toilet and the shower are in separate locations within the place. The view is great, with great light in the evening. Having a washer and dryer is a big plus we highly recommend.
