Stayed a week at the hotel and I couldn't be happier about the stay. The staff, from the people at the front desk, to the room service to the people operating the breakfast and evening bar were all courteous and friendly.
For the price I could not ask for more. The breakfast buffet being on the roof overlooking parts of Rome is an incredible way to start the day, the variety of foods is decent enough and converting the place to a very nice bar in the evening is just fantastic. Location of the hotel is great, metro and busses very close by, downtown historic area is definitely within walkable distance for most.
Only slight issues I had with the hotel were the slightly old decor in the room, most the bed and pillows being a bit hard for my personal taste, but that is very minor. WHEN I go back to Rome, I will for sure consider staying here again.
