WE have a villa there thats only used between March and Oct as i work in London travelling on tube daily, Koca is heaven to me being fairly rural make it more personal with local people as well , my parents who are retired use the villa more than me and have made so many friends out that there that it unbelievable for such a small community.
As for the winter times ive seen the photos and in places is un passable and unliveable at times Although it has got a little better over the last few years i would recommend you have a look before you decide to set up home for there for the winter
i personally don't see this area staying this way for to much longer, as more and more villa,s go up every year talk of a boat yard being built along with a hospital,schools shops and hotels etc, all possibly rumours but strong rumours from the locals
good luck with what ever you decide
