Teresa's apartment is the perfect place to have an authentic Neopolitan experience in the heart of the city's Historic Center. The room is really big (as pictured) with soaring ceilings, overlooking Piazza Dante and with a bigger bed than I'm used to in Europe - a nice plus. It's just 100 meters from the Dante Metro stop. There are LOTS of options for coffee, drinks and food in the area, across price ranges.
If you go to bed early and are a really light sleeper, this place might not work for you, as there is some traffic noise. I'm not a heavy sleeper and I was fine. The apartment is on the third floor, and the room has shutters, windows and doors that close from the inside. All this does a good job of keeping out the light and much of the noise, which was mostly gone by 11pm or midnight during our stay.
Although our Italian and Teresa's English are both practically niente, she was patient and gracious and we always managed to communicate.
The room and the apartment are as pictured, and the place is a great value. I would absolutely stay again.
