Volkan is indeed like a friend you have in a completely new city. Once you book with him, you can rest assured and be at peace. I want to highlight two things: one, this is the best possible location in Istanbul, and two, Volkan is very hospitable and truly like a friend you can trust in a new city. Just book, and let yourself be at peace. I visited with my parents, who are over 70, and the location was perfect as they did not have to walk far to see the most historic sights of the city and it is in a very charming location indeed.
