Location is the best to stay in, as you are in the heart of Istiklal but still its a calm place. The street is safe as there is few coffee shops and bars that opens until late.
2 minutes walk to Taksim square, where you can find the Metro
The room was clean, has AC, TV, small kitchen counter, washroom.
Its all what you need.
For the location and the price it is the best option for travelers who wanna stay close to everything.
