The location is so good, 3-5 min walk to Taksim square, has an extremely amazing view and terrace. The stair up to the terrace is a bit uncomfortable for old people but can be used by adults.
Altug was very responsive and was checking periodically if we needed anything.
I was not satisfied with bathroom standards, but Altug was nice enough to offer us a complimentary Turkish Hamam experience for the whole family.
