I didn't try removing the wheels but that might help too. I would stand the bike up as I manoeuvred between the bathroom wall and stove.
My bike is pretty big so it was the trickiest but once I figured it out it was fine. It helped to have someone hand you the bike thru the door, so you can focus on guiding it through.
You could always throw a tarp over the stove/cabinet while you load up, in case you bump into it.
Anyways, it's very possible to carry 2 MTBs in the 19H.
