We stayed at Matina's apartment for 3 nights.
Is a friendly - very well equipped apartment which I personally think is even better than described.
The location is perfect - just 3 mins walk from Naousa's center (where all the island life is) and you can always find parking outside the apartment.
Matina is an excellent and caring host, willing to assist at all times and provide you an easier stay.
I would definitely recommend it for your stay in Naousa and looking forward to visit it again.
