€350 for a "superior room" which was anything but. (trade fair on in Frankfurt so hotels hike their prices accordingly). Tiny reception area, one lift for entire six floors. Small room, sink in bedroom, no bath, shower in corner. After complaining was told that this was an "open bathroom" layout! No toiletries other than liquid soap dispenser in shower. It was the Steigenberger name that attracted me to this hotel. How they ever lent their name to this dump I will never know. Never again.
