I stayed at Marco's place for 2 nights between my business trip and my cruise trip. I was outside most of the time, came back to place at late hours to sleep :)
Marco's place is exactly as described in his ad; he tends to the place very well, it is practically a full house squeezed into a room. He also spread materials and tips for the city and the neighboring areas for first-comers (I am not :) ), which attests to his attention to keep his guests happy and well-informed. I also noticed with pleasure that he is an Istanbul-lover from the posters providing the most prominent visual feature of the city of two continents :)
In short, I was pleased and comfortable during my stay, thank you Marco
