Christine and Kutay are great hosts and just wonderful people! I spent three very relaxing days in their tastefully and minimally decorated apartment, overlooking the Bosphorus. The room is spacious and very clean, as is the entire apartment. It's not far to the ferry, which you can take to Beykoz (ideal if you're lecturing at the Turkish-German University) or all the way to the city center or Kadiköy. Highly recommended! I look forward to staying at Christine’s and Kutay’s again!
