Staying at Simay‘ will ensure you have a blast while in Istanbul.
Really close to Istiklal, next to topahne station where you can take T1 to Sultanahmet and get all the sights.
The apartment is cozy, fully serviced and extremely well kept.
The area is modern and Cihangir has a lively night scene but still remain very quiet and peaceful.
I went with my 2-year old and he felt and looked right at home.
And most importantly, you get Simay to host you and Gelo you with every thing you need.
Really top notch, and I would recommend this place to anyone planning to visit Istanbul.
