In this design, both apartments have met all the required space.
I hope this plan is both effective and qualified for your needs and preferences.
In apartment A, I applied side entrance for guests, that can be accessed from the main foyer.
This apartment has a big and spacious living-dining room, with a separated kitchen.
I installed a shelf finished with mirrors for the hallway, to make the hallway seems more spacious.
For each baby room, both can access the shared bathroom and shared terrace.
For the master bedroom, it has its own connected bathroom and its own terrace. I suggest the terrace is separated between apartments A and B.
In apartment B, I applied all your needs: two bedrooms, two bathrooms, and a combined living-dining-pantry area (open space).
In both apartments, the style is the same, modern, simplistic with wood materials.
For all the windows and doors, I use dark colors (use dark grey/black) for accentuation.
