The stay at Sergio's was great! He was very friendly and happy to help, gave us great recommendations for food and tips for turism. The place is right at the heart of Naples, short walking distance from good restaurants and bars, and other hot tourist spots.
The only thing that I was a little annoyed at was the size of the shower, it is a 1mx1m, and it was really hard to move around inside. The water is either too hot or too cold, but my husband told me that is normal for the showers he had experienced in Italy before.
Overall, very good experience!
