Very strange to have an Autobahn Reststop/Hotel.. Had to wait at reception while she checked out someone for gum and cigs next counter over.
Note: the 2 Restaurants advertised are a BurgerKing and an Autobahn Buffet, where food sits under a heat lamp for hours...
If you have a choice ...
Go somewhere else.
One night stay on a motorcycle trip. Convenient and clean. It is located on the Autobahn, so you need to have a vignette, however these are reasonable priced and I think worth it just for the view of the lake. Cheaper than hotels non the lake, for sure. Lots of eating options in the restaurant and Burger King is next door, if that's your thing :)
I was a guest of this Ibis many times, and the first time the cleanness of the room (executive, on the 4th floor!) leaves much to be desired. Frankly speaking the room was NOT vacuumed, dirt was on the floor, etc. Front desk when informed about poor state of affairs offered complimentary breakfast, but I declined this "generous" offer...
