We had a really nice 5-day stay in the appartment of Alper. I attended a congress at the convention center (which was easily reached by metro), while my boyfriend explored the area. The appartment is really clean and well equipped. The bed is very comfy (and the sheets are so soft!). Unfortunately we did not meet Alper, but he was easily reachable by phone/text and gave us clear directions on how to get to the appartment.
