This is a beautiful, historic hotel in the centre of Bern, but if you're planning on doing any kind of sleeping, go elsewhere. They even provide basic (and hopeless) ear plugs next to the bed.
I paid 150 CHF for a night here, and checked out within 4 hours. Even with my Sony Noise Cancelling headphones, I had a headache after being in the room for 30 minutes.
Go elsewhere. Find a hotel just a few roads parallel to this one... it'll make all the difference.
Lovely hotel receptionists though, very helpful and friendly.
