Lorenzo is very nice and helpful, amazingly speaks Chinese well. The location is great, in the center of a busy and typical Napoli street. The only problem we had is the stove in the kitchen. It's a little bit tricky, but Lorenzo hurried to help us out even at 11pm. We are really great full for that. Also, the signal is the room is quite weak but you can use wifi to connect to internet so not a big deal.
We loved staying at Lorenzo's place. It's new and clean. Recommend!
