Giovanni gave us the best indications to arrive to the flat, it's only 15 min walking from Garibaldi Central Station but you can also take the tube that is 2 minutes walking from the flat
The flat is perfectly located and you can find any service and hotspot near (restaurants, taxi stop, supermarkets, monuments etc)
Inside Giovanni's place everything was perfectly clean, fully equiped and with many details. The only but is the wifi, it didn't work.
Giovanni took care of us all the time and she gave us many recommendations and provided us all we needed.
I do recommend Giovanni's place for your stay in Naples
