Vasilis and Mira made my stay at the Pantheon absolutely exceptional in every way.
The hotel is located in the old town, moments away from the port, the castle, and restaurants. Vasilis upgraded me to a room with a private bath; the room was simple, clean, and comfortable, with a view of the narrow streets and the sea.
The space, location, and amenities are great, but the most remarkable thing about Pantheon is the hospitality. My ferry was very late so I arrived around midnight, but Vasilis, his sister in law, and Mira were waiting up to welcome me with dinner and a glass of wine. Every day they provided breakfast, invited me to join them for (delicious, home cooked) dinner, and offered tips about the island. When I was visiting, two relatives of Vasilis' were in town and he invited me to join in as he showed them around the island, visiting Mt Zeus and several villages east of Naxos.
I had an absolutely amazing experience on Naxos and can't wait to return with my friends and family, and of course stay at Pantheon Hotel again!
