We just returned from a 3 night stay and it was great! We got a Plat upgrade to a 2 room (Huge!) suite overlooking Via Venetto and the Cafe de Paris across the street. While it may be a long walk for some - but we had no problem in trekking to the Spanish Steps, Trevi Fountain and the Vatican.
We ate in the street side restaurant and it was very good - though not as good as the Cafe de Paris across the street. The bar was very nice with excellent service. We also had drinks at the rooftop bar at the Eden - very expensive but worth 1 drink for the view..........
All in all a great hotel - right next to the US Embassy also!
