I throughly enjoyed my stay with Kubilay. Although he wasn't there the first few days he stayed in touch and made sure that my stay in Istanbul was going smoothly, as well as having his friend meet us and show us the neighborhood etc.
Kubilay is very sweet, trustworthy, friendly and good person to stay with. He is dedicated to making sure that your stay is as good as possible and extremely helpful. Makes for great conversation with a great vibe. I hope to return to Istanbul and when I do I'll stay with him once more!
