If you are visiting Naxos and want to be on the beach, I highly recommend this place. We stayed for 5 nights at the end of August. The sea is crystal clear, the beach is right outside the front door and you can star gaze from the roof at night. The kitchen is well stocked and beach supplies are included.
A couple of notes to help other travelers. I wondered if the road would be busy or would keep us up late at night. In the morning, it is empty except for runners. During the day it is a mix of folks walking to the beach and cars and by the evening it is empty again. So no worries there.
I would come back again in heartbeat.
