When we bought eight years ago we arranged to go into an Estate Agents so they could take us out and show us around a number of properties. There was an English lady working there and when the two Turkish people who were taking us to view, brought out the list of properties to show us, the English lady said to us "I would advise you don't buy in Koca Calis, it was built on a swamp and is full of mosquitos" So, with that advice we scrubbed off all the Koca property. Now, these comments where her's not mine.
We did buy in Calis and are lucky we bought in a lovely spot a cul-de-sac with farm land next to us. So, I would not discount Calis in your search for property, there are some lovely properties for sale in Calis.
