We truly enjoyed our time at Ilkan's apartment and we fell in love with the neighbourhood where everything feels like home and yet has this charming bohemian touch. The location is just perfect, close to the subway and is within walking distance of several tourist attractions. It's quiet compared to the adjacent street but loud noise scooter drivers make at night when passing by might wake you up as the window panes are wooden and not exactly soundproof. The bed is squeaky but apart from these two thing I'd say it's perfect. Ilkan kept in touch all the time and helped us out when we accidently locked the door and left the key inside at night.
To sum up, if you're looking for a place to stay in Istambul this apartment is a great choice)
