Stefano's place is situated in a fantastic location near Piazza Navona. Colosseum, Trevi fountain, Vatican, Pantheon all within walking distance. The area is lovely and feels very safe. Lots of nice restaurants nearby also.
The apartment is as shown in the photos. The rooftop terrace is great while inside is quite small. The bathroom and kitchen unit are cramped as shown but nothing that we didn't expect beforehand after looking at photos.
There were a few additional things we needed throughout (iron, adapter) that weren't there but Stefano was extremely quick in helping us out and supplying one. He responded so quickly to any messages before and during trip.
As other comments say, you must be prepared to deal with many many stairs on a daily basis!
The only criticism I have is that there was a dampness and slight mould issue in one corner the bedroom (this was more noticeable due to a storm that occurred during our stay).
All in all another good AirBnB experience.
