Gasthaus Reber
If you're looking for a clean, simple, and inexpensive room, this small inn is an ideal candidate, located conveniently opposite the railway station for trips to or from Heidelberg. The main drawback: in some of the cheaper rooms, the showers are in the rooms and the toilets are down the hall. In the restaurant or in the beer garden you can order a simple meal for a good price, and there's a terrace overlooking the mountains.
