First of all Giancarlo is a very nice man, we had a 3 beautiful days in Naples ( my husband, my daughter and myself), the flat is situated in a fantastic location, in the heart of historic Napoli, where almost all the sites are.Giancarlo's place is in a typical napoli building with beautiful colors and secured entrance. One thing that giancarlo needs to fix is the little noise of the heater- air conditioner.
I definitely recommend Giancarlo place.
