"The exterior and entrance are beautiful, but that is where the 5-star experience ends. The rooms are nice, yet the windows were extremely dirty and the view was terrible. Breakfast was a major disappointment, more like a 3-star level: industrial quality pastries, undercooked muffins, and poor savory options. Surprisingly, the Ibis near the Istanbul Fair offers better quality and choice for a fifth of the price. The SPA lacks a whirlpool, and the sauna and hammam are mediocre for this category. Furthermore, the noise from the rooftop restaurant was deafening until 1:00 AM, even on the 7th floor. I do not recommend this hotel as there are much better 4 and 5-star options nearby for a lower or similar price. Don't be fooled by the magnificent facade."
