We wanted to live like a local while we were touring Europe so we went on Airbnb to look for a place relatively in the neighborhood outside of the main tourist attractions.
We found Stefania's place near the Universita metro station and within our budget.
Check in was a breeze since Stefania waited for us at the apartment until we arrived late in the afternoon. She did a walk through with me for the entire apartment and had maps of Naples and suggestions for us.
The apartment was located on the 2nd floor of a 7 floor apartment building that came with 2 generous size bedroom, 1 bathroom and a full kitchen/dinning/living room. It was very spacious for my wife and I and we even had a balcony to sit at while enjoying the sounds of locals shouting at each other in italian.
The place provided us with a sense of home so we can cook, make coffee and tea, lounge in the living room and watch TV.
The two down side was the shower drained very slow which made me stand in a puddle of soapy water and we didn't have control over the temperature in the apartment.
Overall I would suggest everyone to stay here while in Napoli because it is conveniently located, clean and provided a home away from home.
