Very friendly & helpful staff (Kozey & the other 2 guys) - apartment is what I expected (clean and you can find all what you want and if there is something missing, the staff will bring it for you). 5 minutes walking distance to the main street and 10 minutes walking and you are in the main touristic places in Istanbul. One downside in the apartment is that there is a weird smell in the toilet (maybe chlore). Also if other visitors are noisy or playing music or watching TV, you will easily hear them. We stayed 6 nights; I personally suffered from 2 nights from other visitors (maybe it is our luck). Thanks Yusuf for hosting us.
