I often stay in this hotel, and recommend it to family and friends. If you get a room with shared bath, the price is in the youth hostel range, for a comfortable hotel with elevator and air conditioning. I usually opt for the private bath. Once my daughter and I reserved a shared-bath room, and the proprietor upgraded us free, because the hotel wasn't full. Another time, she gave us a discount because we were so "gentili".
The family that owns this little hotel, one of several in the same building, lives on the premises, down a hall from the reception. They are helpful in everything. Once we forgot to bring our recharger, and the proprietor lent us one that worked. They will hold your bags before checkin and after checkout, and since they are so close to Termini station, you probably won't have to go a long way to retrieve them.
The lack of breakfast isn't really a big problem; there are plenty of places to get in in nearby Termini station and vicinity. I'd rather have the lower price and get my own breakfast.
