We stayed two nights in Sinan's place and it was pretty satisfying. It is a studio flat, located in the garden of the host where he grows veggies which he uses to serve breakfast and dinner for visitors. Location of the flat is very convenient, only 8 minutes walking distance from the pier. The only small inconveniencies about the flat was the smell in the bathroom(we suppose because from the ventilation) and small bugs(but harmless bugs). Beside from that, the flat has A/C and comfortable bed.
Beside from the flat, Sinan is very smiling and kind person, he was ready to help us in any situation. He has his own small cafe where he serves breakfast and pizza and thanks to his farm, he makes all the food with very delicious and organic veggies. we loved it. We would definitely consider to comeback here next time if to stay in Buyukada.
