This is a great flat, very spacious! Trastevere is a great location, very lively. You may need to close the windows at night due to the noise, but there are fans if you need them. Close to everything! We didn't take a bus/tram the whole visit since everything was in walking distance. Also, there is a yoga studio right next door if you're into that.
Only negative thing was the wifi. Stopped working after the first few hours there.
