We stayed at Enrico's place for a week. It is in a great location, very clean, and a walk away from most points of interest. The room itself is what the British call a bed-sitting room and is really in my opinion, only suitable for a couple. If you open the sofa bed there isn't much space left. As someone else mentioned, the bathroom is really nice, sparkling clean with a bath/shower and really hot water. The kitchen is well equipped although we didn't do much cooking. The large patio is lovely with a great hammock, and the Wi-Fi very fast. There is a small supermarket called "Coop" (it's an Italian chain) 3 minutes away and the area is very safe and quiet, with several commercial art galleries, an antique shop and some beautiful boutiques for expensive clothes. If you like seafood, there is an extremely expensive restaurant almost next door called "Pierluigi's", and we saw well-dressed Italians eating there; we also came across a Michelin graded restaurant in the area, neither of which we went into. The river is a 3-minute walk away.
On the downside, it wasn't really possible to leave the windows and shutters open as other higher-up tenants can see in, so much of the time we left the lights on. Perhaps some light curtains would help.
Read the house rules carefully because you will be charged if you arrive after 8pm. Also check the amenities. There is definite no "City skyline view" - it's on the ground floor surrounded by high buildings; and I don't believe it's suitable for events! Also, no "Dedicated workspace In a room with a door", no "coffee maker: espresso machine", (but there are two small macchinettas), ironing board or hair conditioner. I think perhaps that Enrico just checked everything on the Airbnb list!
However, these small things should not stop you from staying here. It really is a lovely place; Enrico always answered our questions promptly and we met Angela who greeted us. She is very nice and explained everything very well.
