Isabella's place feels more like a little simple hotel than your regular airbnb place, in a good way. It's an old house with really high ceilings and some lovely touches. I liked having more privacy than in the usual airbnb room.
It is next to the railway but the double windows are solid and we had no problem sleeping.
I would recommend the place if you don't mind walking for a while to the city center. You will feel you are staying in Italy!
