The staff is really amazing, and that was the highlight of our stay. We were only in Istanbul for 2 days, and thankfully didn’t have big bags with us, as the rooms are tiny and there is no space to open a suitcase larger than a carry on.
It was warm (travelled in December), and there were no major issues. The room needs a bit of updating and paint, and I tried not to look too much into the details of the cleaning. The bedsheets and towels were clean, but worn out.
