Two colleagues and I stayed at Elif's apartment because it was within walking distance to the venue of a conference we attended. Although we had all different arrival and departure times, Elif was very accommodating with answering all of our questions and concerns. She was always available via text message for any issues which arose. The apartment is very clean, has an air conditioner and wifi, and the kitchen is full of all the dishes and appliances you might need. Supermarkets are only a short walking distance away. It takes about 20-25 minutes to travel to the center of the city with buses, or it is possible to catch a taxi from the taxi stand near the apartment. (Upon arriving in Istanbul, it is definitely recommended to have the taxi driver call Elif for directions to the apartment!)
