Hotels in Berlin with Bathtub

"Spent one night at this hotel in their Single Room, it was big enough for me and the bed I believe may be slightly bigger than a standard single bed, either way it was very comfortable. The room was simple but bright and airy, I would make one suggestion and that is it should have a hook for clothes in the shower room. The most outstanding thing about my hotel stay was the service from the reception staff, all the ladies I communicated with were super nice, friendly and helpful."
