Perhaps in local terms, this is a gem, and that's why I gave it 4 stars. Although the apartment was reasonably clean/comfortable and sweetly furnished, I couldn't go any higher than 4, even after setting the bar at its lowest when making the booking.
The host was very responsive and friendly and tried really hard to make herself understood, but my Italian was just too bad for that. Main issues I encountered were:
1- The address: the provided directions through map will land you in the middle of nowhere. In the maps app, don't use the directions from ABB, but put in the address: "Piazzetta Luigi Settembrini 55". The confusion is "Via Luigi Settembrini" exists in the vicinity, and doesn't have a number 55.
2- Don't count on wifi internet or your cell's. Neither one functions. So you're cut off as long as you're inside the building.
3- I couldn't find hand soap.
4- Although this is titled a B&B, no breakfast was served.
5- Check-out is set back to 10:30 instead of 11:00, and is strictly enforced!
6- Language barrier is a major issue, so don't count on the host being able to provide any help or information beyond what the profile says, which unfortunately isn't accurate. Lack of internet connectivity also doesn't help because no translation service could be used.
Again, I emphasize that I believe per local standards, this is a very good offer. But only if you know exactly what you're getting yourself into. By general standards, I'd give this 2 stars.
