Good: The apartment is great. We were 5 adults (2 couples + 1), and the 2 bedrooms + sofa in the living room was perfect for that.
We always had breakfast in the apartment and the kitchen is well equipped for that. There is also a dishwasher, bialetti and all you need.
There is also a printer, which we needed for our bus ticket back to the airport.
The location is perfect to discover Rome by walking.
Meeting the host worked well. I call him from the airport an he was waiting for us as we arrived (at 11pm).
The apartment looks exactly as on the pictures, it actually feels like home. Comfortable beds, and towels are available.
Bad: since we arrived at 11pm we had to pay extra. We knew it, but still. Compared to other airbnbs, for which you don't have to pay extra...
One of the double beds is not exactly one bed, but 2 beds next to each other. While sleeping it can happen that suddenly the mattress slips away. But nothin tragic...
