I booked a single room with private bathroom for four nights. On the first night, I stayed in a different room because of their double-book. The room had no private bathroom however, that's not so bad. The very clean room had a sink, a big bed and a wide screen TV. I just had to use a common bathroom which was not bad.
After the first night, I stayed in a room with a private bathroom which had a big bed, a wide screen TV, a fridge, a free Wifi and a balcony. It was also very clean.
Every parts of the hotel is very clean. Morning buffet is good.
A Rome Map and a free print service they offer are very helpful.
