Stayed there for a night when visiting friends in Heidelberg. The place is clean and nice, but not worth the 4-stars. The staff was friendly and helpful. Nothing really positive or negative to say about the hotel or room itself. It's 15 km away from Heidelberg and a lot less expensive than all the tourist hotels there.
The only negativ aspect was that we had to pay 15,- EUR on top for having a dog with us. I called beforehand and asked if dogs were allowed - the answer way a simple yes, without mentioning the additional fee.
