My hubby and I stayed at Paolo's flat for 4 nights and it was perfect. The flat was really new and clean just like the photos. The area is quite and nice, but still close to the popular attractions. You can go to Trevi, Spanish square and Vatican by metro without changing to other lines. Also, the homemade guidebook from the host was really helpful!!! Especially we tried some recommended restaurants on the book and they were all really good :)
