Roberta is a good and kind host. We didn't meet in person, but she was always available on the phone. She accommodated our requests, made self check-in very easy and let us store our luggage when we needed to. We loved that the apartment was stylish and spacious. The room was simple and clean. There were some minor things that could be working a little better, but overall we had a good stay. The location is good as well (you can easily walk to many attractions or use metro and train), but at the same time keep in mind that the traffic on the street is very busy and the windows let most of the sound through, so it can be noisy. Though it didn't bother us too much on our 3-day stay. We recommend Casa di Nina as a base to explore Napoli.
