I literally booked this place in the last minute, but Giovanni was really helpful since he replied really fast and gave important information of directions. He wasn't in the house when I checked in; his mom and another girl were there. I spoke broken Italian and they spoke absolute no English, but they are very patient and nice! Giovanni even helped me book my taxi and made sure I could go to the port on time. They are the greatest hosts ever!
The room is huge and everything seems new. Definitely worth this price.
Only one negative thing though - the neighbourhood seems a little chaotic during daytime and a bit dark and scary at night. But I guess that's Naples...
