Furkan was very responsive and whenever I messaged him he helped me out or informed me about something.
The location is great (5 minutes to Levent station which is especially convenient when coming from Sabiha Gökçen airport with the E-3 bus), all necessary shops and the Sapphire mall are in close reach.
The bedroom had a slightly unpleasant smell but Furkan took care of it immediately. Great host.
