Living in a major city we were hoping to stay outside of Rome's city limits to experience Italy on a more intimate level, rather than the hustle and bustle of city life we are used to. Staying at Relais Castrum Boccea was exactly what we were looking for and were so pleased with our stay. It is the best of both the country side and being able to reach Rome in a short time.
To start, he view is absolutely breathtaking. Set atop a hill in what feels the country side (30 minutes outside of Rome), we got the serenity we were looking for. We were able to watch both the sunrise and sunset on the beautiful hotel grounds. Staff was very friendly and helpful. Very delicious pizzeria up the road, less than a mile. Cute little shop to get meats, cheese and wine from a country store. Staying here gave us a more Italian experience than tourist museums and ancient ruins.
My only advice would be if you are thinking of staying here, stay at least 3-4 nights. I suggest this because if you use the van to hitch a ride into the city, you only get ~7hours to explore the city. .By the time you arrive, ~1030 (due to traffic), it does not give you must time to leisurely walk around the city.
*For these trips, trip savings is at least equal to the cost of the flight or hotel if booked separately. Note: For trips including flights, you will be charged by the airline for the flight, but your savings on the trip will equal the cost of the flight.
