Cihan is a great host.
He helped us with all the questions we had and also gave us very good recommendations for places to visit.
He also always responded quick and friendly.
The apartment is very clean and spacious, it is also in the center of taksim. You will have no problems to get late night food and it's only 10 minutes away from İstiklal street.
We can definitely recommend it if you want to have a good time in Istanbul.
