Absolutely amazing place. The entire house is gorgeous, with a beatiful backyard and a stunning view from each and every window. The house itself is located in a natural reserve - it's calm, serene and a great place to go for a walk and enjoy nature.
Hiking trails pretty much right outside the main gate. 15 mins by car to the sea. 10 mins by car to EUR when you can park your car for free and take a metro to the city center. Very convenient, we had no problems with exploring Rome.
The flat itself is spacious, well furnished and it's clear that it was arranged and prepared with care. It has everything that you would need for a long stay. The AC kept us warm during winter, there was a huge amount of storage space, the kitchen was well-equipped, no problems with warm water, washing mashine, super comfy sofas in the living room, with a good quality TV right in front of them.
As if that wasn't enough, Cristiano went above and beyond to make our stay as comfortable as humanly possible. Exceptionally good and fast communication, super friendly attitude, fluent english (and german, and italian, and possibly some other languages :D) - we felt welcome from the first moment.
10/10, should be marked as a superhost.
