Francesco's flat was great for us. The rooftop terrace was something that we thoroughly enjoyed, spending a lot of time lounging in the sun and looking at the beautiful churches that surround his flat.
Check in was great, and he was very accommodating in terms of the time we could arrive. He also gave us some great advice on taking an airport bus that dropped us off a mere 100 meters from the flat.
The flat is also centrally located, around all the great places to see around the city. It is right off of the main street so you have the benefits of being in the middle of everything, but tucked away in a nice quiet area as well.
Will definitely be back again!
