I stayed at Hotel Dufour in Biel while visiting Switzerland for my daughter's wedding. It was a nice place to stay, the only issue I had was with the door at night. The hotel doesn't have a night receptionist and after 12 am you cannot get back into the hotel. However, most of the time this was not an issue for me, but it was a hassle making sure I got back to the hotel before 12 am. Overall, if you're looking for a clean hotel right in Biel for a good price, this is the hotel for you.
