Villa Anson Sil is very beautiful and our group particularly enjoyed the lovely grounds and pool. It was easily large enough to accommodate our group of 15 comfortably.
The location was great, far enough outside the city to be peaceful but with the centre of Rome easily accessible via taxi.
Our hosts, Bernard and Eleanora, were very attentive, very knowledgable about Rome and the surrounding area and full of recommendations from dining options to sites to visit.
They recommended a fantastic local vineyard to us (Terre di Veio) which was one of the highlights of our trip and was very reasonably priced, although when we booked a local restaurant for dinner they did try to direct us to a different option nearly an hour away which seemed unusual.
We were slightly surprised to find some areas of the house were not accessible to our Group, as this was not particularly clear from the booking information.
We also did not find the property very private as the hosts and multiple staff working at the house were frequently wandering around the grounds, particularly in the mornings. They seemed slightly nervous about noise given the size of our group, although we were careful to stay quiet late at night, such that they encouraged us to leave the property in the evenings a few times, which was a shame given we had come to enjoy the lovely house.
There were also some issues with water pressure which seemed to be turned off entirely on our final day.
Overall, however, we were pleased with our stay and our hosts knowledge of the city and passion for their beautiful house was clear. We would recommend to other groups although it may be more suitable for those looking to use it as a base to spend more time in the city!
