Beautiful, large apartment in a fantastic location! Great restaurants/bars like Gurdulu, Dalla Lola, and Il Santino are very close by. The apartment is also a couple of minutes from the lively Piazza Santo Spirito (great for nightlife) but far away enough to be quiet. Comfortable bed, great little outdoor patio, stylish space, and beautiful views of red rooftops. You do have to walk up four flights of stairs to get to the apartment, which didn't bother us but might be a trek for some.
The downsides were 1) the Keesy check-in process and 2) getting in the front door. To check in, you have to download the Keesy app (which added an extra step to the check-in process and seemed unnecessary) and then pick up your key at the Keesy checkpoint, which is by the train station. For us this was on the opposite side of town from where we were before this Airbnb and from this Airbnb listing. The Keesy checkpoint has lockers to keep your luggage, but they were all full, so we wasted additional time having to find where to pay to keep it at the train station instead. Speaking with Keesy support via phone to figure this out was a very frustrating process.
Getting in the front door was difficult - not sure if it was the key or the lock - and it sometimes took up to five minutes of fiddling with it to get in.
Overall it was a great apartment, just wish getting into it was easier!
