We had a great week at Mattia’s place. We stayed there with seven people and partially worked remotely from Napoli. Kitchen and living room can accommodate large groups and the terrace is amazing. In the rooms towards the east, you can be woken up by the sun in the morning.
The location is great if you don’t want to be right in the bustling centre, though the trains and general city noises will be audible (I suspect that’s true anywhere in Napoli though). The nearby station allows quick access to the centre, alternatively you can stroll along the pleasant seaside promenade.
The apartment was clean and communication simple. I’d definitely come back.
