Wow ! Such a nice place...I highly recommend Casa Ravagnoni+++
It was perfect :)
Ideally located, we loved Ryan's artwork all around, the amazing 360°C view from the terrace, the friendly talk with everyone and the nice clothes at Claire's and Fabio's vintage shop.
The room is clean and comfy. Just be prepared to high temperature at night as well...
As other comments say, lots of stairs but it'll keep you fit after pizza party and anyway, it worth it.
I would definitely come back !
