Great spot as advertised and reviewed. It’s 68 steps up and down each time. The automatic lights at each floor didn’t work perfectly but after your first time on the stairs you know where you’re going.
The outside patio is great. There’s not a real view from it but the outside fresh air in the evening was nice.
I will stay again when I go back to Istanbul. Five minute walk to Taksim Square, Istiklal street and the metro/funicular.
