Just to add my 2c
Last time I was in the MO,we had a suite,I couldnt recall the name of it but it had the shower in the bath.
The bathroom was big but no separate shower.

This time we were in a bog standard Courtview room or at least thats what I think it was called and again there was no separate shower.

Bad - yes!
Though we didnt mind so much.

Different story in the four seasons Prague-beautifull riverview room in the old building and yes a separate walk in shower as it should be [ we opted for that after.. other than the MO -Vuittons ]
The 4S prague while I'm here-excelent service and just immaculately kept.We were not impressed with the michellin star restaurant though-poor wine list-tiny portions [compared to other michellins we've been to and bland food].
