Chiaras apartment is very conveniently located, a short walk from trestervere train station, and walkable to the bars and restaurants of trestervere and testaccio.
Chiara is a very friendly and responsive host. I felt she would be quickly available for any needs.
The shared space was kept tidy, and we never actually encountered the other guests. The shared wall of the bedroom was quite thin though, so you can hear conversations next door. Still great value for money.
The internet connection is good. I had 50mbps download and 40 upload. I had to take some work video calls and it held up. There's a good shared working / study space nearby in testaccio too where you jusy have to pay 5 euro credit to spend in the bar.
I would stay here again.
