I wish they mentioned about having no lock on the door to my *private* room so I could be aware of and at least consider preparing a pod lock or something. Caterina was not available to check me in and Antonio, Caterina’s partner helped me. Though they were very nice, I felt uncomfortable not knowing exactly who are there sharing the flat. (I saw at least 3 other people who seemed like tourists, in the kitchen next day)
I also regretted my misjudgment of choosing a room with no AC in the summer, in the 40℃ temperature. There was a fan in the room, but for me it was not much of a help. By opening the room window, you could have a little bit of breeze but also lots of noises from the busy street.
Still, as everyone mentioned here, the location is great, right next to the famous square, so if it’s not summer time or if you actually don’t mind the heat, and also a room with no lock, I think, for the location alone, you would enjoy staying at Caterina’s. Even though the building is very old, Caterina keeps the room (and kitchen and bathroom alsomk) very clean.
