Marcos place is excellently located! Pretty much all the amazing pizza places are within walking distance. We went to sorbillos (a recommendation from Marco) and it was by far the best pizza we’ve had.
The area felt very safe, we walked around happily at night and we walked from the apartment to the train station with our cases with no problems.
Forget all the rumours about Naples - it’s a fantastic city :D thanks for having us Marco!
