I flew with them in August, from Geneva to Varna (via Istanbul and Constantza - NOT a route to be recommended).
They were absolutely fine. It was a novelty to be served hot food and I could have had whisky for breakfast if I'd wanted! Service was fine and the aircraft were clean and comfortable.
Istanbul was fine - plenty of shops if you have time to spare and like that sort of thing, but on the return leg it was incredibly crowded, hopefully I just caught it at a bad time.
