I have to say chose to stay with Sinef and Tolga is one of my luckiest thing of my trip in Istanbul. They are super nice and friendly person.
Sinef is a very cool lady she brought me out some local place to experience the local Raki~Which is a very memorable moment of my this trip.
The location of their house is perfect. 2mins walk to metro ,marmaray and bus stations.
The room is on the second floor you will have enough privacy. Outside the room there's a very big balcony the view is amazing.
There's a cat and dog and also Sinef and Tolga's lovely daughter in the house. Unfortunately I couldn't speak Turkish so I couldn't communicate too much with this lovely cute girl.
I really wish could stay a bit longer but it's time to go home.
I wish your family all the best. Hope I can come to visit you guys soon in the future!
Best Regards,
Evalen
