Salvatore has been a super helpful host, fast response when I had problems. The place was very clean, looked like just renovated. It's a bit lousy, as it's on the ground floor, facing a road. AC is on the living room, so it can get a bit cold in the bedroom.
We faced a couple of problems: the electronic code system wasn't working when we first got there, but Salvatore was very supportive and solved the issue in 5min; the toilet water tank was probably missing its cover, so when flushing some water was drizzling out of it. As we were the first guests, I'm positive that Salvatore will fixed this issue.
Location was nice, not exactly central, but 5 min walking from Metro station "Materdei" and 15 min walking, uphill, from piazza Dante, where there is the best nightlife in my opinion (piazza bellini) and best restaurants (spaccanapoli, via dei tribunali, via toledo).
It was a pleasent staying, i recommend.
Ps: very nice drinks, candies and italian coffee offered by Salvatore :D
