Barbaros is supposed to be very nice. One of our guests had a week there and a week in our apartment, and she spoke very highly of it. However I agree about the pool, it really is tiny.
Part of the Ozcan hotel is on the beach, but I have heard mixed reports about it, someone we met was staying last year AI and they said the food was awful, and the hotel really basic, but then it was an extremely cheap holiday. They have a pool by the beach but I believe there are only chairs not sunbeds by the pool, so if you want a sunbed you have to go on the beach.
The Turunc Hotel is on probably the best part of the beach, I'm not really sure what its like there at the moment. I'm sure you could find lots of reviews for it. It also has a water park which opened last year, that is also open to the public, but very expensive.
Don't recall speaking to anyone about the Mavi Deniz, it is in a nice position, and I think the pool is quite good.
