I have been in this appartment for 1 month and all I can say it's good. I rented a car at the airport (I highly recommend to rent a car to reach this house) and I could move from the house to the rest of the island. Naxos is amazing and at the port there are really good restaurants. The views from the house are amazing.
Only cons is that there is no heating system (so the house it's cold) but Nikos says it in the advertisement, so no issues.
There are cats in the surroundings that I fed daily, so I hope the next guests keep feeding the cats that are at Naxos.
I hope to come back! Nikos is a easy-going person, I recommend his appartment.
