First time I came to Istanbul with my wife, we had found Guner's apartment after 1 day bad experience with a very dirty apartment elsewhere near Taqsim square, what a shock and the difference is huge.
First, the apartment is clean and cosy
second, the communication is perfect, you can finally communicate in proper English
Third, the location is perfect, you are very near Taqsim square and in a quiet neighbourhood where you can have a very needed sleep after a long day full of touring around
as a bonus, you get vouchers for breakfast at their own cafe down the road.
did I mention communication? yes and around the clock, very responsive host! I decided to cut our vacation short at night and I could check out in the early morning no problem.
All I can say is that, we are glad to find this gem of an apartment in Istanbul, truly a value for money
