The studio is located in the Asian part of Istanbul, and even it seems far from the historic center, it is close to a stop of many buses and for about an hour you may reach the city center. For my purposes it was perfect! It is not big but enough. Situated in a big beautiful building, quite secure!
Orhan was very easy to communicate with, I received all the information I needed. And it was a nice surprise that he had left for me sweets, fruits, water and juses!
In general I had a nice stay at Orhan's place and strongly recommend it!
Thank you Orhan!
