The apartment is a v clever conversion of an old smithy; interesting and artistic. It was remarkably warm despite its high ceilings - a boon for winter travellers from much warmer climes.
Our group consisted of 2 couples and a single adult.
The en suite upstairs is fabulous, but the adjoining bedroom is a thoroughfare for the en suite dwellers (it would be ideal for younger children).
The sitting room downstairs was converted into another bedroom (curtained off from the hosts' private studio/storage). The upstairs sleeper can lean over a waist-high wall to interact with those sleeping downstairs (this level of open-plan living may not suit everyone).
The two bathrooms and two loos were great.
We were able to walk into the city and Tier Garten which was v convenient.
