Bianca is an absolute dear, I really can not say enough good things about her. She was very helpful with any questions I had. Provided breakfast and to world's best coffee, even got up early the morning I left to offer me some. The apartment large and comfortable, with a great view from the patio. The room was great equally large and comfy, I really felt at home. Just make sure to close the shutters to cut down on the noise and get rid of the glare from the street lights (took me 2 nights to figure that out). The apartment is right next to the historical part of the city and a short walk to the water front.
When you go to Naples, stay with Bianca. You'll be glad you did.
