All in all, this was tactical apartment for us. It's close to the center, close to the station, close to many restaurants (that are top quality) and very connected for us to go to Etna. However, a few things kind of decreased my overall rating: (1) the unproperly mean of waste differentiation which is important to me where organic & paper was mixed; (2) the sharing with Salvo which wasn't something we expected when reading the information. The apartment is advertised as Entire Room and nothing is mentioning that it is shared. This wasn't an issue, as Salvo is a delightful roommate but took a tole on our privacy expectation. (3) When advertised as old monastery for some reason I expected something more antique, clean and historical but none of that was meeting my expectations. That's on me though.
Other than that, it was tactical and a good location to stay at in Catania if you're passing by only. I had no issues sharing with Salvo and the presence was barely felt and the room is very comfortable with a good bed (important for me when travelling). I would recommend!
