We stayed in this hotel in October 2006, and we were really pleased. The rooms are all different and really beautiful. It is a little bit out of the centre, so at night you have to take a taxi to get back to the hotel, but the upside then is that the area is really calm and quiet. For my wife and I this is perfect after a hectic day in a city.
Jacuzzi in all the bathrooms. The hotel has a deal with a taxi company: 40 euro to Fiumicino Airport (really good because by train you already pay 11 euro per person, and a taxi is much more convenient).
Great location (near the Tevere, area of Testaccio and Trastevere, lots of bars, restaurants etc.), fantastic rooms incl. jacuzzi, wonderful breakfast - a truly fantastic place to stay in Rome!
