I helped my brother and his family to Burak's place in the Sisli Nisantasi area. and my brother plan to return to that place when vacationing in istanbul. The location is very pleasant and very close to the center of the Nisantasi crowd. Burak is a friendly and responsive host, he even provided free mineral water and also some things for the kitchen needs during our stay and was friendly to ask if there was anything needed and he can help. quite pleasant to stay in a clean, modern and cozy place with reasonable price.
