We have just been to Hasan's place and it was great. The location is great as you have Metro, Ferry service in 10 mins walking distance. There are many restaurants nearby where you can pop in any as a trial basis. Istanbul is only 25 mins away if you go by ferry. It saves you money too. With regards to flat, it's a nice studio with a reasonable price. The flat is clean and tidy. They also have office in the ground floor so any issues, it's easy to communicate with them. We also have found the people are nicer over there.
