It is perfectly located in Eminonu, near the Bazar and the most important sites as the Blue Mosque and Aya Sofia. We did not meet personally Sinan, but he was always available at the phone and really helped us a lot. Extraordinarily flexible with check in/out. Only two recommendations: he will try in any way to help you to find the place, but it has been for us extremely hard (arriving after 11 pm, the whole area around is deserted, dark and ghostly, you will not meet anyone and can really be scary)
At 4 in the morning of the second night there was an unpleasant episode, after several noises one of the structure tried to enter the room, only after we realized that he thought the room was empty and available for new guests just arrived
