Marco's place is as on the photos; clean, spacious and in quite a good location. It is about half an hour walk to the historic centre. In 5 minutes you can easily reach one of the best pizzerias in Naples - "Pizza Starita". The neighbourhood has everything you will need for an independent stay - pharmacy, grocery shops and two supermarkets, all easily and quickly accesible.
The only issue we had during our stay was that Marco surpriced us with trying to charge us €2 per day per person, so in total €28 that wasn't included in the Airbnb price, that we thought was not so honest. Fortunately, we managed to settle that between us and Marco paid it from Airbnb price.
Overall, it was a lovely time and the apartment and hosts helped us enjoy Naples to the fullest.
