Merve is a lovely host, she was always in touch and ready to help with any question, apartment was good also, located in peaceful area, not so far from the sea and close to marmaray and other transportation :)
But unfortunately i cant give five stars to this place, in the evenings Merve often invited guests who was talking and smoking in the living room, and usually it was quite noisy till the night. There were problems with water in toilet and shower also.
