we stayed at this double tree in july, worked out well for us. short walk to all the sites except Vatican. we did taxi to Vatican and another from there to Spanish Steps. nfrom there walked our way back thru Trevi etc to hotel. Sadly the last night we found our favorite restaurant and its a very short walk from hotel. La Fata Ignorante Rooftop Restaurant & Bar, its on the roof of IQ Hotel. I say we found it sadly our last night because I could have eaten there every night. our first night we were tired from traveling and just across the street from hotel is sidewalk restaurant, not 5* by any means but very good lasagna etc. two entrees and a bottle of wine $25, it was a good end to long day.
