I enjoyed my staying and appreciate help from the host, Can and his mother Subiler, his sister as well.
I stayed a spacious room at the 2nd floor and used a big bath room as well mostly alone.
His house is surrounded by forest green area near the old castles and the ocean sea side Bebek areby 6 munutes walking distance.
I may book Can's house again in 2020 next year when I get back to Istanbul in 2020 next year.
Wush Best luck to Can and Ms. Subiler, his sister as well.
