Firstly, Giacomo was by far the most accommodating host I've ever stayed with on Airbnb. I had some specific requirements around the contract registration, and Giacomo truly went above and beyond to help.
We stayed in the apartment for 3 months, so got a very solid feel for the place. The location is one of the best in the city. Piazza Navona is literally at the end of the street, 5 minutes walk to the Vatican and all the subdistricts like Trastevere and Monti are a short walk away. Despite all this however the area manages to feel quiet and cozy, not overly touristy.
The apartment itself is well equipped, with good insulation in the windows to keep it surprisingly quiet. A good quality TV (very handy during lockdown periods), full kitchen and charmingly decorated.
