We enjoyed our stay at Filiz’s space.
Location is very central and quick access to public transport.
You can find any shop around the apartment in a walking distance.
Very nicely decorated living room; lovely dining table and book shelves. Wifi is available, good tv system.
Filiz is a welcoming host and she was very helpful.
Overall, its a good option if you dont bother to use transport for reaching main locations of İstanbul.
Travelers with car (if foreigner) may face difficulty to find a parking place.
