We love this place!
Location was perfect, very central, close to ferry station, and quiet enough for Kadikoy. You can walk to everything from grocery to bars to boutiques to Internet cafe within minutes. Local cats are VERY sweet. A cute tabby frequents the nearby block, absolutely recommend feeding her ;-)
The apartment feels like your grandma's 90s Soviet bloc house, very homey with a lot of plants, miscellaneous decorations, cups and plates of all styles etc. etc… Living room has large windows, very bright even on cloudy days, sea view is just like the profile photo 100%.
Laundry and dishwashing will be a bit tricky if you're used to American style large washing machines/ dishwashers. But they worked okay for us after some trials and errors.
The door can also be tricky. Do remember to ask Sibel to show you how to open and lock it.
