Gulnur and Aslans appartment is located close to cembaritas tramline and a KM away from sultanahment tramline and major site points.
We took their cab which I would suggest as it will take close to hour and half to reach their place as the IST airport is far away. We were greeted by the caretaker who checked us in. Although we had different languages we were able to communicate
Aslan was always available via WhatsApp and he suggested places to buy Turkish delight and baklava as well. He helped us in resolving many queries. We stayed in appartment 4 which had a partial sea view and more than spacious for a small family of 3. TV and phone didn't work however we didn't mind about it as we never used it other than checking it.
There is a slight uphill and downhill walk but we enjoyed the stay as the appartment was as described with all the amenities available inside the appartment. In all a great place to stay in Istanbul.
Will surely recommend friends families and all
