Location Q: Ep.1 The red brick 2-3 storey hotel?

Presumably somewhere in Belgium as IMDB and BBC both cite location filming here and the exterior architecture and interior period details are very European?

To me, this red brick house (hotel as it is cast) looks very Bavarian/southern German.

It's the location which has the INTerior with the brown bear in the lobby. Where is this interior? Does an IMDBer recognise it please?

Ditto (I'm not sure the interior location equates to the scene setting EXTerior shot/location implied by the production editing however??), where is the red brick 2-3 storey building?

TIA any kind IMDBer assist :)
