The flat is very well located, only seconds away from the Trevi fountain and a 15-30 minute walk to all the most famous sights of Rome. The check-in process and communication with the host were very smooth and pleasant.
The apartment was very clean, offers all necessities and is definitely a good and comfortable place to stay at for a couple nights when visiting Rome.
Note however that the flat is badly soundproof, you can hear street noises and conversation from the neighboring apartment very well so if you’re a light sleeper you might have to reconsider.
