Pro - If you’re traveling from the main Hbf station you can’t go wrong with this hotel straight across the street in a safe neighborhood. Clean, looked new, modern, comfortable bed.
Con - It’s nice that the toilet is in a separate room with closing door, but I didn’t like the lack of privacy in the shower room which has no door. Adding to the problem, there’s a mirror in the foyer opposite the shower that reflects the person showering. The hotel should consider that two people sharing a room with separate twin beds are possibly colleagues and are not desiring to watch each other shower. Perhaps in your twin-bedded rooms, you might move the mirror to the back of the WC door and/or consider installing a curtain or shower curtain that can be drawn across across the entrance to block the view.
Overall, enjoyed the hotel.
