This place is a gem,
It's perfectly located between the seaside and Taxim square (five minutes walk to each), in Cihangir, a yuppie/hipster neighborhood,it has its unique style though. Pretty and unpretentious
. The flat looks exactly like the pictures, and has everything one would need for a prolonged stay (i stayed for a month) - fully equiped kitchen, washing machine, tv, speakers and whatnot. Its clean, and comfortable.
Rana was very helppful, and very knowledgable about istanbul and Turkey. She went of her way to help in any possible way.
