My wife and I spent 5 nights at Luca's place and had a great time. The location is within walking distance to most sights, although it's not directly in the center. Luca's father helped us check in, and we didn't really have any issues. I would say that this place is suitable for 1-2 adults, but more than that would be too cramped. One other thing to note is that if you are a light sleeper, the noise from cars on the cobblestone street outside may be a bit noisy since the apartment is very close to the road. Overall we enjoyed our stay at Luca's place.
