I took a group of adult student of Italian to Rome for hte weekend and found this hotel on the internet. I managed to book everything via email with them. When we arrived, there was a bit of confusion with the room allocation, but, once we got over that, we were very pleasantly surprised by the size of our rooms - they were HUGE! Even the single rooms, were spacious and had a balcony. The hotel is clean, the breakfast was good and the staff were really helpful.
The hotel is located near the underground station Policlinico, but if you are going to/from Stazione Termini, there is a bus that only takes 6 minutes, so make sure you take that instead. less
