Villa Mousa is the kind of place that deserves more than 5 stars. In addition to the breathtaking panoramic view of Naxos, the unit is well-stocked with comfy furniture and everything you need for a great stay (including pots/pans/coffeemaker/etc). Mike is an incredible host, and his friendliness and hospitality went above-and-beyond. We also loved the location: amazing private-feeling beaches are only a short walk (5-10 minutes) from the villa, and the nearby taverna, bakery, and grocery store (~1km) are both convenient and delightful. Note: the walk does include a somewhat steep hill but if you're in good walking condition it's totally doable. If you're mobility-challenged or dislike walking a car you might prefer a car.
All in all, Villa Mousa was a highlight of our stay in Naxos and in Greece! Highly recommend!
