I feel bad giving reviews like this, but it's important for future guests to know.
The host was very kind, she also greeted us with some local bakeries.
The apartment is in a great location, in a residential area in Naples, very close to stunning views of the city.
Interior design is also good, and it was clean.
My only and biggest problem was that the apartment is located in the basement of a building and it smelled horrible. It was very damp, it smelled moldy, like you'd expect a basement to smell like but not an apartment where you sleep. I dreaded going in there and it irritated my throat to be inside for the whole night. You could also feel the dampness on the bed sheets and it was not a good feeling. There was only one window, in the kitchen. We constantly left it open but it wasn't enough to bring fresh air or light inside. I was also a bit anxious sleeping underground, with no windows nearby, so if you'd be bothered by that I definitely wouldn't recommend staying here.
