Now, now. You can't just call it un-comfy just because of that.

Compare it to a 'comfy' home in the same era, which has:

• Drafty wattle-and-daub walls and leaky thatch roof

• Smoke filled rooms

• Rats everywhere

• Flea-filled floors, walls, and ceiling

• Toilet is a hole in the ground outside

In this case the movie version is closer to reality than your "realistic" version. Castles were not just built for defensibility. They have a strong representative aspect. Of course they made them as nice to live in as possible. The walls were covered in tapestries or wood panelling and many rooms were heated. For unheated rooms there were movable heaters (basically small portable fire pits).

Heres an example of a hall in a castle: https://de.wikipedia.org/wiki/Tr%C3%A8s_Riches_Heures#/media/Datei:Les_Tr%C3%A8s_Riches_Heures_du_duc_de_Berry_Janvier.jpg

I have extensive experience with castles and this does not mention they are very bouncy & come with slides

Sure the toilet is a hole in the wall, but it beats shitting in the moat.

The acoustics in those castles must be horrendous too. Just shit echoing all over the damn place

It must be warm inside to attract the rats

The wall? Surely it was in the floor. It would he awkward as hell to shit through a hole in the wall.

Don't forget that the benefit of being a noble was sleeping in a big group on a cloth covered sack of hay in some filthy flea-bitten body odor nest.
