Getting Spa in Istanbul

Hey guys.
I'm about to get a Spa Center in Istanbul. Do you have any idea about which place in Istanbul is better for this and what kind of new things I can do in Spa to be different than others.
Thanks

You'll have two choices. Either the spas in the hotels. ..or traditional Turkish hamams.

Depending on your choice, you'll find either in your area. Pick the four/ five star hotel closest to to you. .or a Turkish hamam in your vicinity. 

Good luck
