When we first arrived, Sinan's team was there to help us with our bags, they were very helpful and very kind everyday!
The studio was very clean and the view is amazing! The location is perfect, it's near everything : Eminonu , Beyazit, tramway, Grand Bazar..... The streets are very animated during the day but at night it's empty . My advice if you would plan to stay out late at night, would be to take a taxi to come back home. But Sinan's studio is definetly worth it for a stay in Istanbul!
