My husband and I stayed here for a 10-day anniversary trip to Naples. The place was amazing - historic, wonderfully located, quiet, well-appointed kitchen, and clean. Luigi and Rosanna were wonderful hosts and very accommodating when a missed airline connection forced us to arrive much later than planned. They also suggested many sights to visit and places to eat.
The apartment is right in the midst of the historic center which makes for great wandering and puts it only 1-2 blocks from the main streets with all the restaurants and activity. Yet, the apartment was nice and quiet. There isn't really a living room area to hang out in, but the bedroom was large and the kitchen had a good-sized table so it was easy to relax in those locations. Possibly tight for more than 2 people, but perfect for us.
The online description of the place (and photos) is fairly accurate (I don't think there are two bathrooms, we only saw one which was good-sized with a shower). It may not be clear in the description, but the apartment is on the 3rd floor (4th by American counting) and there is no elevator. This was fine for us but might be a concern for others less mobile. Luigi was very kind, helping us with our luggage.
We highly recommend the apartment and would happily stay here again!
