Unfortunately we are fully booked for this winter but I can give you some insight on other alternatives;
-if the cost is yr primary concern, Yatmarin will probably the least expensive option. You can get all kind of technical service
but not always the best + it's a bit far from the center if this does matter for you.
-D Marin Turgutreis (Bodrum) is another option but they will be quite expensive.
-Göçek and Netsel (Marmaris) are even more expensive and have limited spaces for hard standing.
-Kas and Finike can quote better prices but they are quite far from the airport
and basically no technical service
All in all, if you just need a basic works on the boat or no work, you may want to stay in Greece; it will be much cheaper than anywhere in Turkey. PM me if you have any other specific question.
