In the room I chose, the curtains were not tight. Although there were iron gates outside the window, the light would still penetrate into the room, so I had to tie a knot for the curtains. Because we were tired and wanted to have a quick rest, we found that the plug of the washbasin was blocked when we washed, and the water could not flow down. I had no choice but to go downstairs and find the staff. Fortunately, the staff immediately changed a room for us.
