Comfortable, albeit in a semi-shut-down-due-to-corona kind of way.
I was there on a Sunday night, and there was nothing open - no bar, no amenities, it was just the room. I'd had a late appointment and I wanted a beer at 2215, and the receptionist said they weren't allowed to sell me a beer at 2215; I don't know if that is a general Bayern thing, a Sunday thing, or a Corona thing, or a combination of all three, but I was annoyed!
I'd stay there again sure, but it was just a little bit closed and so slightly difficult to rate fairly.
