I stayed at Merve's place for nine nights and it was one of my best experiences with Airbnb. The apartment is conveniently located yet in a quiet street, functionally furnished yet stylish, and above all, very clean and spacious. You can easily explore Beyoglu/Karakoy by foot with all its design boutiques, third wave cafes, and nice restaurants. Metro (Sishane) and tram (Tophane) stations are nearby, so is Istiklal Caddesi. Communication with Merve has always been clear and smooth. All in all this is a great place for both business and leisure. I highly recommend this apartment and would love to go back when I am in Istanbul again.
