Have been to Naxos 3 times, and this is my best accomondation so far.
Perfect location, 50 meters from the beach, and a 10 minute walk to the port and city centre. In the other direction, is a 5 minute walk to a big supermarket (where you can buy fresh meat and other things to make som nicce food in the equipped kitchenette) and bus-stop which takes you to all the beaches. The location is almost at the end of a road, in a quiet and green area.
Many of the rooms have nice view over the beach, and BIG private balconys (som rooms have a smaller balcony). The sun shines directly on many of the rooms during the day, so it can get hot, but there is aircondition on the rooms (free of charge).
The host Nikos is very friendly and helpful, and the cleaning of the rooms is very good. There's also a small bar in the reception-area, but i've never seen any people there (maybe because the balconys are so nice).
I'll come back, for sure
