OK stay because of the good location (close to Duomo) and the unique building (high ceilings).
However, it's a noisy area (old building and old windows, so no acoustic isolation).
The fridge and "kitchen" are common to the entire floor of the apartment hotel, which is also not specified anywhere.
Also - If you check in after 21:30, they ask you to pay 30 Euros, which is not specified in the listing at all.
