Hi,
we have been there in December/January. In Bafa Gölü there are some pensions, where you can rent a room. In Winter it should be quite cheap. It is not very easy to find boulders, because there are not many climbers around, so you won´t find very much chalk or other traces. You will have to walk around and see if you can find something. For a beginning, there is some information in german at:

Some bulgarians created a new sector at the end of the road to the west with some very good boulders.
You should have a car, because there are only tiny shops in Bafa Gölü and it is hard to reach.
There is also a film about bouldering there, it´s called "Herkleia". Nice bouldering movie from the US.
The landscape is amazing, the bouldering not as good as let´s say Switzerland or Fontainebleau.
if you have more questions, pleas contact me.
Peter
