I was in Lucios apartment, Via Toledo, Naples for 5 days. The place is absolutely perfect. Very clean, spacious, light and well looked after. There is everything you need, and even lots of food, to use in the kitchen. The location is in a nice area, right on the big shopping boulevard, and just next to the area "spanish" with all the narrow streets. The old city is around the corner. It is close to the metro and busses as well..
Lucio is such a nice person and he is a great host. He is reliable, makes you feel very velcome and will help you with anything if you need it. When I come to Naples I will stay in Lucios apartment Again.
