Our stay here left us with a mixed impression. The apartment itself was clean and is furnished nicely. The location is absolutely amazing within Trastevere but also Rome overall. We did not hear any significant noise from the street while staying during the week.
However, everything that is not known before booking turned out to be less favourable. The checkin procedure is extremely complicated. We were required to provide an exact arrival time 2 days upfront and had to confirm it multiple times via AirBnB and a 3rd party messenger service. Unfortunately, self-checkin is not available. In addition there are various specific house rules with predefined fees attached that are never agreed upon before making the reservation. Lastly, the Wifi seems to be a mobile hotspot that turned out to be slow (about 5 Mbits) and does not reach to the bedroom.
Overall, we would still recommend this place to a couple on vacation during weekdays.
