I would say it is more a hostel with private rooms/bathroom than a hotel. If you go with that expectation, it will be a good stay. Hotel and rooms are old, but the bed is confortable and staff are really nice. Breakfast is kinda messy, since there is only one person doing the cleaning and the food, but if you arrive untill one hour before closing time, you will find good pastries. And the possibility of leaving luggage after check out for small price was really a good deal.
It have great localization, walking distance from all touristic points (even Vatican if you enjoy longer walks), near train and subway station, and with cmarkets and good restaurants nearby. Considering the price for the localization and with breakfast included, I think it’s good cost-benefit.
