The location is great, in a quiet residential area (great for light sleepers). It's on the west side of the Tiber river, but still within walking distance of most tourist attractions. Also just a few blocks from the main restaurants in Trastevere.
The apartment is the right size, the kitchen is small but functional. The bed is comfortable. The new windows are awesome!
We dealt with Daniele, and communicated well via WhatsApp. He was very friendly and provided good restaurant suggestions.
We loved Rome, and it was a very positive experience.
