First, even they mention this in Accessibility section, but they should list out "Access to upper floors only by the stairs" in the summary since this is really important to the people. If I've knew this, I wouldn't book it.
Second, they should have more wall-mounted coat/towel racks and more clothes hanger since if you're going to dry your wet clothes and hang your coat/towel at same time, you simply can't. They should also consider to put a wall-mounted hook on the door of bathroom so people can hand their towel there.
Third, the amenity rack is too high to reach to the top layer, they should provide a stand stool.
