Nice studio apartment in an apartment complex up on the hill - so be prepared to walk quite a bit. The apartment itself has a courtyard balcony which is nice and sunny from late morning till afternoon and is equipped with all the essentials including a dishwasher - it is clean, the bed is comfortable, and at night it is quiet.
We were a bit worried about the check in as the communication was only in Italian and didn’t say how to get the keys- but the check in was super easy: we were greeted in the hallway and handed the keys. Check out was at 9:30am and easy too. Keep in mind that in all of Naples there is a tourist tax of 2,50€/per person per day.
