The hotel is close to the train station, which was the reason I chose it, because I only had one day in Naples, and had a train to catch the next morning. The airport shuttle also goes to the train station, so this hotel was very convenient.
This is a basic and cheap place to stay, don't expect anything fancy.
The area around the central station is a bit shady, so if you are a nervous traveller I suggest you find another area to stay. That said, I didn't have any unpleasant things happen to me while I was staying in the area.
The room and the hotel is just fine. Clean and big rooms. The best part about my stay was the guy working the reception and the kitchen, really nice guy from Sri Lanka.
The entrance to the B&B is hard to find, because they only have a super tiny blue and yellow sign on a gate into what looks like a regular tenant building. There is no elevator so you have to carry your luggage up 3 flights of stairs. I was a bit nervous when I was walking up the hotel door, wondering what I had gotten myself into, but when I rang the doorbell and was greeted by the nice receptionist, and got to see the inside of the hotel, I was relieved.
All in all, a great and practical stay if you're just passing through Naples.
