Leonardo was a great host. We never actually met him but he was very responsive and willing to help. He made recommendations of local places to eat and even offered to make reservations for us. He also offered calling for a taxi when he knew we were leaving very early in the morning. There are two sets of steps from the entrance, can be hard to climb after going to the top of the Duomo but it's all worth it as the bed is super comfy and will definitely help resting it out. The shower is also really really nice with great quality pressure. The apartment is very well located at around 10 mins walking anywhere and very close to the trams that go to the airport and the trains if you want to visit other cities too.
The neighbor next door likes to talk and sing loudly in the hallway in the morning and another neighbor put very loud music one afternoon, I'd say that was the only thing we didn't like and that's not Leonard's fault! Still, it was a small nuance in a very nice stay. Would definitely stay again.
Thanks, Leonardo!
