Nice, clean and modern apartment in the calmer part of Trastevere, which made it an excellent choice for us. The host, Devid, was very attentive and responded quickly to our questions and also helped us with transportation to the airport.
On the downside, a very thin door separates the apartment from the neighbouring one and with a bit of unluck and noisy neighbours, it could be difficult to get a good night's sleep.
With that said, we still certainly recommend both the apartment and Devid as host for a stay in Rome!
