Have a look and, if you want, I can make the reservations. If you make your own reservations, make sure you get the University special price.
Rica Travel Hotel
This is downtown, but Bergen is not big, so there is just a short walk to the campus.
I am holding 5 double rooms at this hotel (160 cm bed)
University price: NOK 779 incl breakfast
This hotel is very close to the university and next to the park at the campus.

I am holding 5 single rooms as well, but these are small

Raddison SAS Hotel Norge
The hotel is downtown and probably the best of the three. I tried to make reservations for 10 double rooms and they are available all days except June 14, but they will let me know if there is cancellations.
In case you want this one, please make an alternatative as well.
