We met them in Calis a couple of years ago for a drink. They had encountered lots of problems with the house in Uzumlu and were desperate to sell.. Sylvia would not drive in Turkey and Les was then unable to drive at night.
We did have a phone number for them that no longer works, so we assumed they had managed to sell and had gone back.
I know Angel at the Nil was very friendly with both of them and she will probably be able to give you more details.
