We had a fantastic stay at Barbaros' place. It is in a relatively decent location in the old town with everything <15 minute walk away. It was also easy for taxis to find our location with the nearby hotel as a landmark. The place was clean, well-stocked with basic amenities (e.g. shampoo, body wash, tea, towels), and provided enough space for 4 adults. The place is well-organized with enough hooks, plug-ins, seating space, and lighting. Unfortunately, there was some noise from people upstairs who had two young children, but this may have been out of his control. Overall, if we were to come back to Istanbul, we would definitely consider booking again.
