I visited Istambul with one of my good friends. We are both girls and we wanted a place close to the major attractions.
Gulnur's place is sparkling clean, and very comfortable. It is walking distance to major sites and public transportation. I got a lot of help from my hosts, they helped me arranging the transportation to and from the airport. Also they were very very nice at me . Also they left me food for breakfast which was very helpful as I arrived late after a long trip .
At night we went out /dinner in other areas of the city. The neighborhood at night can be very alone specially late but we used ubers and everything worked well. The area is not suitable for anyone with mobility problems and you have to work up hill and up stairs.
I will definitely come back!
