I found this hotel on-line and was a bit worried. it turned out to be very nice, clean and cozy. the staff was friendly and the room comfortable, and not very expensive. we paid 75 EUR.
we only stayed for one night so it did the job. we were on our way to Europa Park, which is an half an hour away, Freiburg it self seems to be a nice place to visit, and it's close to Basel, Strasbourg and the French border.
