We stayed a week in Mario's house. And we loved it. 4 adults and 4 children, age 11-14 had a great time. Nice charming house with 4 big bedrooms. The house and the kitchen, had everything needed.
Most of the time, we were on the terrace, playing cards and enjoying cool drinks or in the pool. The pool is a nice size, both for relaxing and having fun.
The view over the hills and Civita di Bagnoregio is spectacular.
Mario is kind and very helpful host. If something came up or if we had any questions, he came as soon as possible, to make sure everything was good.
The road to the house is very steep, but nothing a regular car, can't handle.
There is a lot of noise from the cicadas all day long, but in a way we got used to it.
For trips we can recommend the Civita di Bagnoregio and Cascata delle Marmore near Terni.
