I've stayed at 5 different Airbnbs in Rome, and I'm not sure this bnb currently meets it's value proposition.
The positives:
Amazing location, can't be beaten really if you want to be close to the best neighborhoods for exploring and food
Luca is relatively responsive and certainly seemed nice.
The negatives:
Janky check-in. The electronic door lock was not working and Luca did not respond for ~15 min while I tried to get in. When he did respond he said he would be there in 20. After 10 min though, another guest conveniently came home and let me in. They said that the electronic lock was also broken for them earlier that morning, even though Luca insisted that it was working that morning. Host-less checkin is the most important thing in an Airbnb to me, so this is a big negative.
Cleanliness
The apt was not thoroughly cleaned. The shampoo and soap that the previous guest(s) had used was littered on the shelf next to the shower. There was hair on the tile, and the walls indicating that it was not cleaned very carefully if at all really.
Expensive for what you get. At this price point, for a single person or couple, a low end hotel will provide better value.
