The pension is a 15 minute walk from the cathedral. The room is really small but for just sleeping it's fine. The walls are very thin. Though there wasn't much noise from the outside (not many people walking by) you can hear everything and everyone inside the pension. I didn't get much sleep two out of three nights since guests arrived and/or left or showered between 1 and 3 o'clock in the night (I was wearing earpads). So expect it to be loud from the inside not the outside.
The bathroom is a shared one. I didn't have to fight for my turn so that's good considering there are at least 4 rooms sharing one bath.
All in all it's a good place to stay if you don't mind tiny rooms and loud noises in the middle of the night.
