I have just returned from a 3-day stay in this hotel as part of a 48-strong group. Apart from the fact that you enter a time warp when you go in - the rooms have old-fashioned washbasins (two of them!) in the bedroom and REALLY dated bathroom facilities - we were amazed at just how rude the staff could be - notably two older ladies (one was the owner I think) who sighed and tutted when asked anything, and took great pleasure in banging plates and sundry cutlery down in front of you if you dared to sit on any other than your designated table.
It was almost funny - a sort of female Fawlty Towers - but needless to say nobody mentioned the war!
I used to live in Germany some years ago so I can vouch for the fact that this is in no way typical....
