We didn’t meet Eirini in person as she had to travel, but her friend Dimitris was really helpful and patient in explaining to us about the apartment.
Eirini’s place was wonderful - all the amenities you need are available and there were also snacks and breakfast items in the kitchen. If you want to whip up a meal yourself, the equipment are there too.
The apartment was really clean, but just a tad far from the center (approx. 10-15 min walk away) so the street can be a little too quiet at night. That said, Eirini did offer arranging for cab transfers from the port.
Overall, we really enjoyed our stay in Naxos and in Eirini’s apartment and would recommend her place to anyone who’s visiting the island!
