Rena was very helpful- she arranged our transfers to and from the port & airport and the porters. The porters were great. This was especially true as the stairs were steep and it would have been challenging to get there with our luggage on our own.
Rena also printed out our boarding passes. We had a very early flight and yet everyone rallied to get us to the airport by 5:30am.
The cave was lovely and comfortable and stocked with breakfast cake and wine and juice and coffee. The two decks were wonderful places to hang out in the morning and to end the day.
The musty smell isn't there all the time, only when the dehumidifier is full and there is a cleaning person who changes it daily. So that is an easy fix.
The walk to the launch for the kayaks is long and the launching area is not great for swimming. We would highly recommend Amoudie Bay for swimming in Oia.
Also, if you are feeling a need for a different cuisine from the traditional fare, Paradox, the Thai restaurant, is quite good.
