We enjoyed our stay at this kadıköy apartment very much.
Guven, very best managed our stay, quickly responsive before entering and after leaving.
He communication in English.
The apartment location was very appealing to us. 10 min away from all transportation options (subway, ferry, autobus etc.)
Also close to the bus station near the piers from which you can take the shuttle bus to either of Istanbul's two major airports.
The apartment itself is pretty spacious.
The main bedroom is large.
Huge thank you for best experience in Istanbul.
