First, this is more of a "apartment hotel," than an Airbnb.
The communication with the "host" was great and easy. She arranged a van to take us to the airport very nicely (at extra cost ofcourse.)
The Location is close to Duomo, but on the opposite side to the shopping streets (over 1.5km) The walk to the apartment is not that far (400-500m) but the road is rugged so it is VERY hard to drag your luggage on.
The apartment is nice and spacious.
The bathrooms are quite old. The upstairs bathroom's shower is just barely running, very hard to shower with. No soap or shampoo in the shower so bring your own. The towels seems clean but smells like damped cloth.
While the living room and downstairs bedrooms are nice, the upstairs are a bit different. The stairs are very creaky, making is very loud to get up and down.
The wifi is very stable.
