David's flat was perfectly located! His father, Riccardo, and his uncle were there to meet us and show us everything we needed to know. They were incredibly sweet and helpful.
We ended up in the "IRIS" flat, which I imagine is very similar to the APT. DAVID flat we booked.
Plenty of room and sofas to spread out, hang out and relax, after a day of running around.
The wifi was a little confusing - had it some of the time, but would not connect much of the time.
Although it seems close to the train station, and probably could be walked to from there, I would definitely suggest taking a taxi to arrive for 2 reasons: 1)the cobblestone streets will be crazy to drag your luggage through town to get there, and, 2) the address is impossible to find if you haven't been there before, but our taxi driver knew exactly where to go, just by us showing him the address.
All in all - great stay! Lot's of room!
