I had 4 wonderful nights in Isil's apartment. She's responsible for all her guests, arranged her friend to wait for me until 1:00am when my first day arrived. You can get all informations about Istanbul from her, transportation, where's the best place to visit, best restaurant, etc. Isil is a super lady, i felt so glad to chat with her and shared with her my stories. The apartment is located in a historical residence area, i enjoyed watching the kids playing on the streets from my window at nightfall. This place is highly recommended:)
