If you are looking for a quality place to stay in Besiktas, then Orcun is recommended. The double bed with very comfortable padding and 2 medical pillows were there, which is not all hosts have! The towels were fresh as well. Basically, everything you need is available in Orcun flan. I just forgot something ! Orcun is a very easy going person, who gives you the space to do whatever you like with no interference.
Check in and out times were very flexible and Orcun work with a trust ethics that I really liked about him.
