Guven is helpful, fast response and courteous. The room is what actually I expected, it is very convinient enough. The location is located near Bosphorus ferry and Uskudar marmaray, just a walking distance from his home. He and his girlfriend are friendly. We made a plan to hang out around Uskudar on my final night, but unfortunately I was in deep overslept, however he made an effort to have a nice conversation with me before I check out. I recommend and sure will contact him if I go to Uskudar.
