In fact, it's a flophouse with minimal amenities. There are no 3 stars in sight, at most- one solid star. The only advantage is the convenient location next to Termini train station. Many of Rome's attractions can be reached on foot. The disadvantages are a micronumber without sound insulation, a microscopic shower, low water pressure, it is rather warm than hot. It's not cozy at all. It would be fine if such a room cost 80, maximum 100 euros. But 170 euros per night for "this" is considered an overprice.
