Great house, great location and a very helpful host. We had a lovely stay. The location of the house is perfect; one minute walk to the seashore. Bakery, mini market, grocery store, pharmacy and many other shops just around the corner. There are also several playgrounds nearby, closest just 5 minutes walking distance away. Sarıyer is a lovely calm and relatively less touristic district of Istanbul in my opinion and the house is right at the seaside where you can have a lovely walk or jog along the path or have a boat trip to the other side of the Bosphorus.
The house is beautiful; old but very well looked after and well equipped. You can see the sea and Istanbul from the top floor while sitting on the sofa even! The only thing is the basement layer is colder than the rest of the house, so we needed to use extra blankets (which were already provided) and needed to warm the house a bit more at night. Everything else was perfect and everything in the house was in great working order.
