Cagri was an excellent host, he spontaneously wrote us how to get to his apartment and proposed to come to pick us up. The appartement is very well located, just 3 min from the galata tower, close to the old istanbul, just the galata bridge to cross and close to the new istanbul.
The apartment was very clean, with all commodities and with a small balcony with a view on the Bosphorus.
Cagri was very helpful and answered to all our questions during our stay and it became a friend and we had a good night with a few drinks together the last night we were in Istanbul.

I would definitly recommend a stay in this apartment. I would to precise also that unlike some other apartments proposed in Istanbul, this one is a 'real' apartment where Cagri lives and not a business which makes it much more comfortable and clean.
