We stayed in this apartment for almost a month. The apartment is located in a great and vibrant area, just 5-10' by foot from Taksim square and 5' by foot from public transportation. If you're travelling for business, you'd need to know that the wifi is very fast and can cover your business needs (e.g., online meetings). Everything was clean and Mustafa even offered a free cleaning service in the middle of our stay. The most important thing is the fact that, for anything you may need, Mustafa is responsive (he usually replied in a few minutes) and will be there for you. When we'll visit Istanbul in the future, we'll definitely choose one of Mustafa's apartments. Highly recommended and thank you Mustafa for the great hospitality.
