I stayed in Buse’s flat for 5 nights. It is located half way between osmanbey and Taskim metro stations. Easy walk to either. Also close to Havaist airport bus.
Flat is on top floor and is very comfortable. Buse is quick to respond to questions. I walked out without the key once and he arranged to get me in within 1 hour and laughed it off. Very kind
Overall good vibe!
