I'll try to be as fair and factual as possible about my stay:
The apartment was very clean and just as described, apart from the fact that I was expecting a two-persons bed instead of an individual one. I then found out that this was mentioned in the description; the price varies depending on the beds used. I didn't read it through and only stopped at the pictures. My fault! Read the description carefully and make sure to mention how many people will be there, even if it's just a friend who'll stay over for a night or two.
I visited Rome during a cold period of the year. The heater is put on automatically from 6PM inside the apartment, but even then it got quite cold at night.
I was welcomed on time by Sonia's mother. She showed me the place and how everything worked. My checkout also happened as described: her father came to the apartment exactly on time. Both were very nice and warm.
The area is quite nice. Some restaurants/cafés serve breakfast and there's a pharmacy as well. Ordering food for delivery is also possible.
Last but not least, the apartment is quite far from the center. This can be a good or bad thing, it really depends on what type of traveler you are. I went out almost every night until late and getting back home was a real struggle. I spent about 2 hours per day in buses and metros, and when the way back home seemed too complicated, I just took a cab which cost me 20 euros each time. In the end, I think it wouldv'e been the same had I taken a more expensive Airbnb but closer to the center. Every bus that I took was at least 15 minutes late and I missed almost every connection when there was one. It's even worse past midnight. One night, I took a direct line home at 2AM and the bus was 45 (!!!) minutes late. My point is: don't count on the fact that there's a bus stop just in front of the apartment. Getting to the center and especially coming back late in the night can be quite challenging.
Overall, other than its location, the apartment was quite enjoyable: the kitchen and bathroom are big and the bedroom has a large window with a terrace.
