We found Nesibe's place to be a perfect AirBnB to explore Instanbul. It has been decorated in good taste and has a lot of character to it, with a window looking out at the sea and a seagull coming every morning to ask for some food.
We also believe it is a great base to explore the rest of Istanbul. Cihangir where the AirBnB is located is itself a very lovely place, so we often spent our mornings wandering through its maze of streets. It will also take you roughly 15-20 minutes to reach Bosphorous and the old town. The apartment is situated in a very lively street where there are a lot of cafes and restaurants. The only downside in terms of the location is that it can get rather noisy on Friday and Saturday nights from nearby restaurants and cafes. The good news is that it is quiet in the bedroom and we could sleep well.
The apartment is also good for long-term stays. We spent a month here and had all our needs covered. There are two tables you can use for work. The appliances like vacuum cleaner and iron are of really high quality.
The host, Nesibe, helped solve all our problems and was a great resource on things to do in Instanbul.
Overall, I would rate our experience 5/5.
