Bahri and his family are great hosts. We have stayed for a week in this amazing city and Bahri's place made us feel like home because it is a cozy apartment with everything you need, from a stove to a juicer and it has this wonderful view over the Sea of Marmara. It is located in a quiet neighborhood with at least three supermarkets in less then a 100 meters and a lot of small places where you can eat with the locals away from the busy tourist crowded places.
We have especially enjoyed the morning and evening short ferry rides to the European side and back. It was the perfect time to feel the sea breeze and to start the day.
You should definitely consider Bahri's place and you won't regret it.
Thank you Bahri for your hospitality and thank your wife for those little gifts. They made our evenings on the terrace even better. We will definitely stay at your place next time we are in Istanbul.
