The apartment is modern and very clean. Chamber kitchen and bathroom also met our expectations. Surroundings may seem dangerous, but it's just the wrong impression. It is very safe here, and the Napoli Central station is close (1.8 km, 20 minutes on foot). After a day of sightseeing this apartment is a real rest for the weary tourist :) And Carolina is very helpful and nice person. Our stay in Naples was very nice.
Ps. I highly recommend the use of the bakery, which is on the ground floor of the building (bread is cheap and delicious). Right next there is also a vendor of vegetables and fruits.
