Claudio's apartment is beautifully renovated and very well-located near Naples'tourist center. There is the University metro stop not very far away, but you can also walk to a lot of different destinations. For the most part extremely clean and well-maintained but we did have a small bit of trouble with the showers. Claudio also switched us to the bigger apartment in the same building, so this review will likely appear on the one we booked originally.
However, I need to say that overall this is an extremely good value - the apartment is well-located, beautifully renovated and Claudio was a very helpful host. In this price range (or even a slightly higher price range tbh) I really can't imagine finding anything better.
