We were traveling to Mykonos via a cruise ship and made a reservation with this company for an ATV rental and tried to cancel the reservation three days before our arrival date because the weather forecast showed rain. We emailed them and they said it was too late to cancel - why three days notice is not enough is beyond me. Of course, on the day of our arrival it was raining. However, there was a break in the weather and we went on to the Island hoping to squeeze in a ride. We walked all over and asked some local businesses where they were located -- go figure, no one ever heard of them and they did not provide us with an address. There were PLENTY of car, ATV and scooter rental companies within 6-7 minutes walk at the bus station. I would suggest going with them - at least they have a physical location. Of course, they refused to refund us our deposit. Would NOT recommend them!
