We stayed at the Sheraton Voyager in Antalya the day/night before a flight. It's a very modern and quite impressive hotel (we stayed in December and the centre atrium goes from ground floor to top floor so you can stand in reception and see all the floors and roof and they had a 50ft decorated christmas tree up the middle of the hotel)
It all sounds very expensive and I suppose for Turkey it was a little, but for a family room in a Sheraton we paid about £58 from memory. When we got there the receptionist said he could upgrade us to a corner suite for $10! We took him up on that and had 2 bedrooms, 2 bathrooms and a view to die for from the huge corner balcony.
It's not an airport hotel, about 15 minutes taxi to it, but if you want a bit of European quality luxury but don't want to pay £200 a night, the Sheraton is superb. Only 10 minutes walk to McDonalds too lol
