Extremely memorable views of Istanbul, and we found the bed to be extremely comfortable with good quality sheets, and two well-functioning AC units to make for a very comfortable stay. The hike up the stairs is no joke, but as other reviewers say, worth it in the end. I didn’t find it to be loud at all at night in the back bedroom though the street is quite busy as soon as you step out.
A quick tip! Check out “yakto ipek dokuma” down the street for some really high quality locally produced textiles. And SALT Galata a few blocks away would be an excellent place to get some quiet work done if you need :)
