Stayed six nights at this Holiday Inn Express. It is about a 15 to 20-minute walk from the Hauptbahnhof. It is a huge hotel. Check-in was easy, and the staff was very helpful. I believe there are about 300 rooms at this hotel.
The room is quite large and has all the amenities one would want. There are ample plug outlets. The bed was very comfortable, a large TV, and of course, good wifi. There is no sound outside of the room, so a good night's sleep is pretty much guaranteed.
A buffet breakfast is included in the room rates. There is ample food and a large variety to choose from.
