This one was one of the greatest stay with Airbnb. The place was great and and very clean. Everything was close by and very close to Metro stations.
However, what made my stay great was the host of the house. I had a child who was very tired due to flight and asked him for an early check in and he helped me straight away.
In addition, he was very helpful with check-in and out date alternation which was very helpful as my plans were changing day by day due to my circumstances and he was always very helpful and supportive. This is what makes great host like Olcay.
I would definitely come back at his place if I ever travel to Istanbul.
