I highly recommend this apartment. Lucia is a wonderful host, very reactive, accommodating and kind. The apartment was clean, very well organised and comfortable. No wasted space anywhere, and very nice decoration. Lucia also provided for breakfast, and really knows how to make you feel at home.
It was really really hot in Napoli when we visited but the apartment was fresh, and there was AC if we wanted even fresher (admittedly, we used it a couple of times, and half an hour of use was enough for refreshing the whole apartment).
What's more, the emplacement of the apartment was perfect! Not very far from the subway, and honestly, you can do so many visits around on foot since it's in the center. It's also close to some really good trattorie and pizzerie !
Next time we come to Napoli, we'll definitely choose again this apartment!
