We spent three days at Carmine's place and that was one of the best Airbnb experience we had.
Elena and her mum greeted us at the gate and showed us the flat, which was sparkling clean and cosy. There's everything you need in the kitchen and even in the bathroom. We found freshly picked lemons on the table and on our last day we even had the sweet surprise to receive delicious Napoli pastries sent in a basket from the balcony!
The location is 5-10mins away from the metro station, which then reach center Napoli in 20mins. Very convenient and also run until around midnight. We could thus leave the car and go on our own. It is also fairly quick to reach Vesuvio, Pompei and we even pushed it to the Amalfi coast.
We definitely recommend Carmine's place if you want to explore Napoli and surroundings
