We had a very nice stay at Cate's place. She was very friendly and gave us some tips about the area. The situation is perfect: it is a nice neigbourhood, and well located for the transports.
The room is not very big, but it's perfect for a weekend. The street is beautiful, there is a lot of choice if you want to eat, have a drink, have a good ice cream.
I think the quality/price is perfect. I would recommand this place for anybody who wants to visit Rome for a few days.
