My family - four adults and one toddler - really enjoyed over a week here and would happily stay in the same unit again. The apartment is larger than it appears in photos, and the view is great. We enjoyed the local treats as well!
Host was very responsive and helpful. We experienced a night of rain (rare in Naxos) and parts of the ceiling near the window leaked slightly and showed water damage, and one of the heater/AC units was hit or miss (though each room has one and Angelika also provided a radiator if we wanted it). I believe these are normal "historic building on the beach" problems, and didn't dampen our holiday, just things to note.
The walk to the ferry port is just a minute or two, and several good stores and restaurants right across the street, as is the edge of the town's most charming area, which is clearly visible from the huge veranda. Views to the Portara and Grotta beach are fantastic, and anything you might want are an easy walk, even with baby in tow.
We have already recommended this place to friends.
