It was a very pleasant experience staying at Simone's place. We were able to check-in early at around 5:30am without any hassle. Simone explained the self check-in process in a very detailed manner.
The location of the apartment cannot get any better. There is a nice bakery at around 50m from the apartment and duomo at 8mins walk.
I would definitely like to stay here again and will also recommend it to my friends.
