My girlfriend and I stayed in the apartment for 4 nights.
Awesome location. A couple of minutes walk from the Colosseum. Also there's a bunch of bus services and a metro station at the Colosseum that will take you all over Rome. There were also supermarkets, restaurants and bars nearby.
The apartment was clean and tidy. The room had abit of an odour but is to be expected with the old building, air purifiers are supplied.
Giacomo checked us in and was great. His communication with us was top notch. Helped us out to find a few things with instant replies.
Definitely recommend.
