Onur is an excellent host,very fast in responses,kind and helpful.His apartament is in the center of the city,with plenty of shops and restaurants in the neighborhood.It is not a touristic area,but is authentic with really nice people living there.Apartament itself is very comfortable with an amazing see view.It is a very clean and spacious place,where I felt immediately at home.It is so easy to explore the city from this spotThe bus stop is 100 meters away and takes you directly to Taxim sqare.Another bus can take you to Sultanahmet area,where most of the holistorical sites are.If you are a light sleeper,then maybe in summertime with open windows,the noise from the traffic can disturb you but other than that this is an incredible place to stay while in Istanbul!
