A really nice place, as described, conveniently very near istiklal street, the Galata Tower, restaurants and cafes, and the metro. What I love most is the design and the view from the balcony overlooking the sea.
The place may not be suitable for everyone: the very narrow final staircase (almost like ladder) to the loft, the bare wall & ceiling industrial design. But it was definitely suitable for me and I loved it.
Would not recommend travelers with big suitcases unless physically in shape. I only had a backpack.
Samet was very communicative and always ready to assist with information. A great host!
