The apartment is a little smaller than the photos suggest. Some of the ceilings are very low so there was a need (at least for me at 5’11) to always bow my head for fear of a concussion. Otherwise, the space is neat and tidy, the bedroom generous and the kitchen adequate for cooking.
We stayed across a a Friday night, so there was quite a lot of noise, at least from the living room that serves as the second sleeping area.
The apartment is really handy for local bars, restaurants and cafés, they are (literally) on the doorstep and the vibe is quite relaxed, although a little overpopulated with tourists during the evening.
Overall, we had a good stay there and would definitely stay in the Trastevere area again.
