The apartment is right near Galata Tower. A lot of restaurants around, easy to get there (just say Galata Kulesi in a taxi - done). The rooms were clean and atmospheric. But the wooden floor sometimes bites your socks, because it has tiny splinters in some places. It wasn't bothering us too much, but if you have good socks, you will be sad to tear them. To sum up, the apartment is nice with a view to the Bosphorus Strait.
P.s. Special thanks to Gokcen! He was waiting for us 2 hours, and during the checkout he arrived at 7:00 AM!!!
