I spent 5 days at Giancarlo's place, while visiting Rome with my parents. The apartment is a 5-minute walk to San Pietro (you can see the duomo as you walk outside of the building), 5-minute walk from bus no. 64 (easy to connect to Termini or other spots in town) and very close by there is a large Carrefour, open 24/7 ( there are also some restaurants, and small charming shops). The place itself is very cosy, well-equipped, quiet and confortable, in a safe area. Giancarlo was very welcoming, waiting for us for our check in and sharing valuable information (best places to eat, best ways around, the portable wi-fi - which was great to have with us during our long walks).
I would definitely stay here again if I get the chance, and I wholeheartedly recommend Giancarlo's place - which feels like home while in Rome :)
Thank you!
