We rented 5 separate apartments at the Castello for 10 days for my 50th birthday. Guests arrived at different times and for various lengths of stay. Fabio paid attention to everyone in the group that needed it and was a fantastic host. We were deeply impressed by the hospitality and kindness of Fabio, of Giulio the owner, and of the several permanent residents of the castle grounds. We find it so amazing that Fabio finds the time to run a modern estate farm on the one hand and tend to the needs of giddy tourists on the other, but he does it very well. Bravo. Large events are discouraged in the AirBnB profile, but we had a discreet birthday dinner outside for 19 people, and Fabio helped by supplying extra tables and chairs. ____The apartments at Castello del Duca make a marvelous combination between city and country. Looking out of your window you imagine yourself in the middle of the Roman Campagna. The castle grounds are well kept, but still rustic and typically Roman. Still, you are really in a suburb, with a convenient train line and connections to the major freeways. The grounds are perched above the surroundings and give great views of the Tiber at sunset, but are also susceptible to the sounds of trains rushing by. We were not really bothered by this. After all, it isn't deep countryside here. But it's certainly quieter than Rome itself with her millions of tourists. _____All 6 of the rental units are unique and are in old buildings scattered around the central castle core, which is still a residence. The grounds are completely open to stroll around, including the castle courtyard and little ornamental garden. Il Conte has the best views and breezes; Il Duca is the largest and most elegantly furnished; Il Marchese next door is smaller and has the charm of country cottage; Il Visconte is in an old single storey outbuilding, has an ample living room and a broad view up to the Castle (it's also a bit closer to the roads below); next door Il Barone is petit but romantic; Il Cavaliere has a large raised private terrace. ______Enough choices. We would happily return to Castello del Duca.
