Hi there we stayed at the oasis a couple of years ago and it was really nice at that time Oracle in the resort centre near the roundabout where the horizon hotel is on the corner. were selling the properties.
They are fairly near to the ruins of apollo and didum shops etc are five min walk away. Its roughly ten min walk to centre of altinkum and there is a free courtesy bus which I think was running every hour between the complex and the resort centre.
If I can be of any further help pm me Jacqui
