The overall cleanness of the room is great. The staffs are friendly and 24 hours of reception service is helpful given the quality of German Railroad service.
However, there are not many items (Coffee, tea, kettle, working desk, etc) being provided in the room with the price paid. The breakfast selection is basic but with good food quality though.
The location is not within the walkable distance to the airport and requires public transportation or hotel shuttle service. Part of the elevator of the connection bridge to the bus / train station is not working properly during my check-in, but this cannot be blamed to the hotel. A 10 min walk to the station requires passing through an open land and this can get really messy if it rains heavily.
I would recommend this place for those who doesn't want to take a chance on the railroad / bus service if their flight is in the morning, or who need a rest at hotel after picking up the rental car.
