A great place! What you see is what you get.
The location is really great. It’s 3 minutes from the Golden Horn riverfront, 15 minutes from Galata tower and the closest ferry station. At the same time the place is hidden from tourists, it’s in some sort of a local market bubble (mostly building materials), so by the end of the day shops will be closed and the neighbourhood will be quiet. However, during the day all streets can be parked really heavily, up to three cars in a one-line street.
The closest restaurants are aimed at market workers, so the food is not overpriced. A lot of fish places and fast food near the Golden Horn.
The communication from host was helpful. They respond quickly, whether you need something repaired or want to order cleaning service.
