Hakan`s place is the perfect location for exploring Istanbul. Besiktas lies in the heart of the city at the Bosphorus. Other parts of Istanbul - such as the old town and the Asian side or the Taksim area - are reachable within 20 minutes by bus, ferries, and tram.
Hakan is a very pleasant host. The flat is very clean and he has very helpful recommendations for everyday life matters in the neighborhood. The neighborhood is another big plus. There are a lot of small coffee shops, restaurants, bars, and book shops around. It is also a great place to work. I will definitely try to stay there again for the next time. Many thanks Hakan!
