I've booked a quadruple room for my son and I in the Youth Hostel, so there's 2 bunk beds available for 78ChF (about £51) in total for the two nights (Wed 16 and Thurs 17) per person, including breakfast. Not sure if you have to have an up-to-date youth hostel card - if you do, it's only £15. Even then, it's only a total of £66 for 2 nights accommodation with breakfast.
