For many years we have worked with high level Tour Operators such as "Voyageurs du Monde" in Paris and you can find our yachts on their website. Their faithfulness is the consequence of the quality of our services.
Your criterion of choice should not be only the price.
Since 2016, we created a Facebook group for our passenger's reviews, as TripAdvisor deleted us end 2015 (TripAdvisor is normaly deleting all excursions that last more than one day). You can see the most recent reviews following this link : https://web.facebook.com/groups/greecebysea/
The advantage is that you can contact directly our passengers (please do not abuse). The disadvantage is that may be you have not Facebook :-)
That's why we also show here the last first page we had on tripadvisor :
