Highly recommended! Ms. Melis's apartment is located in the heart of Nisantasi area, new, very clean and gorgeous. Not only that but also, almost will take you less than 3 min walking to the metro station. Has all necessary appliances and kitchenware that you need. It's very stylish design and excellent Internet wifi. Ms. Melis is very friendly and helpful person that would really offer anything to assist you in any matter.
Definitely, my next visit to Istanbul next time, I'd stay at her property again if it's available without thinking.
