Bedroom:
The coral tree is not actually what the baby TARDIS looks like, but it's vaguely similar, and in that place/height. The wood thing at the far left going off of the edge of the photo is the table/desk for the laptop, and about where the kitchenette starts. The wooden structure is a rocking bench, not a crib. The furniture is there, but not the random stuff. The flowers might be, but if they are they're silk, like the ivy.
Bathroom:
Kitchenette (part of bedroom, just offscreen):
Layout:
The actual room is slightly smaller than some so that part of it can be used for the water, to make it look like it's submerged. There's nothing living in the water, just fake things, and a light designed to look like sunlight filtering through it (which can be turned 'off' to simulate something more night-ish) and the bed mostly dominates the whole dry room/suite.
