We were 11 co-workers who decided to visit Istanbul together. We managed ok with sleeping and shower arrangements. The apartments are in a great location, in the heart of the historic city, although they are on a side street and so they are very quiet. Two small cafes are next door which was ideal for breakfast and a cup of coffee. Our hosts did their best to suggest various activities and Erdem even went along on a boat tour and lunch with is. He is surely one of the most hospitable persons I ever met. It was also my first time using airbnb, so he was a great guy to trust. I left feeling very grateful for his time and effort.
