This place is located in the heart of the Naxos port. The sea-side balcony is amazing, great views of the harbour. You have everything at your doorstep: pubs, restaurants and shops. One tip is to double check with Σπύρος which studio you are booking (there is sea-side one, which is visible on the photos, and a side one which is nice as well but does not have as great balcony view). Σπύρος and his mother are very welcoming hosts.
Highly recommended!
