The first thing folks should know about this hotel is that it's 3/4 mile past the last stop (Drusdal) on the 3 tram, and the bus to Alte Dursdal (the hotel's bus stop) is notoriously unreliable. There's supposed to be one every hour after 7 pm, but it never came (nor did it pass me as I was trudging up the hill). If you like hiking uphill at the end of a long day, this place is cozy enough and the price is right.
On the other hand, getting into Kassel is easy, if not quick, and iMountainpark made for a nice place to come back to. There is no food except for breakfast and no place to shop, so you have to get your meals in Kassel or someplace on the road.
