We was at Biray's home for 2 week and it was perfect! Great host, great location, lovely cat! It's in the center of the Istanbul and you have everything you need - shops, fish markets, mall, places to eat, metro and bus stations. Apartment is worm and cozy, fully equipped kitchen, WiFi. Biray is very friendly and she respect your own space. She is very clever and nice girl - glad to meet her!
I highly recommend it!
