This apartment is simply beautiful--the styling of each room, the beautiful tiles in the kitchen, the lovely linens and the high ceilings. Just gorgeous. We were in Rome at the lodgings in the middle of July, and my only complaint is that the single air conditioning unit simply could not keep even the bedroom cool, much less the sitting area, kitchen, and bathroom. It was about 35 C outside and the bedroom wouldn't get cooler than about 28 C (82F), so if you are sensitive to head I'd suggest another place OR avoiding the hottest part of the summer.
The location was great, a short walk to Vatican City and an easy bus ride from many other great sites. Claudia was very responsive when we had a problem with an appliance and was flexible about our arrival time. She also coordinated a car ride to the airport to facilitate our early departure from Rome.
