At reception, a relatively small sign indicates that room service is not available for stays of less than three days. There is no information on why this is the case. It can be applied for a day in advance, but otherwise the guest is responsible for cleaning, making beds, etc. There is no personal note at check in. There is also no discount for this service, which is actually common in all hotels.
The hotel bar closes at 22°. The rooms are worn out, the beds hard and slack. The breakfast is not particularly shiny either. How a chain like Steigenberger can allow this is a mystery to us.
Conclusion never again!
