We had a truly amazing experience at Niko's place : his apartment was very well equiped and clean, ideally located in a quiet yet convenient neighborhood (free parking, beach, restaurants and supermarkets nearby, easy way out of town with a car, reasonable walking distance of the city center) and amazingly maintained (daily cleaning of the flat).
Nikos and his team were very helpful to us at all time of the day, he was also very reactive in his communication with us and full of small kindnesses (advices about hotspots in town, lending of a sunshade, little present on our departure...), thus we had the feeling of living in a five stars hotel :-)
This was definitely our best AirBnB experience so far, so we can only confirm that Nikos is very worthy of his "SuperHost" status and we warmly recommend his accommodation to anyone wanting to enjoy the full Naxos experience !
