"Good staff"

Good staff, very helpful. They respond very quickly.

"Booked a boat tour"

Booked a boat tour. Very simple to do and very good support when I had questions about the trip.

"The boat was on time and it is a…"

The boat was on time and it is a beautiful way to see the coast along Naxos. The beach in Koufonissi is gorgeous (Pori) and the food too.
I would not have minded leaving 30 minutes or 1 hour later to have more time in Koufonissi. Taking the boat to visit the beaches is awesome!
And of course the staff is always kind like anywhere you go in Greece! Definitely worth the trip! Just make sure you know what to do in Koufonissi ;-)

"Solid Agency!"

Zastours effectively arranged my bus tour of Naxos and was very communicative. I would definitely book additional tours through them!
