The interior arrangement concept is not much different from the existing floor plan that you provide.
Some of the things I redesigned include:
1. I move the laundry, so that activities in the bathroom that tend to need privacy will be more awake.
2. A wider shower area.
3. Placement of a bedroom with a solid partition in the middle of the unit is the right choice because it requires privacy, considering the window / door to the balcony is very transparent. TV is on a platform that can be directed as needed. can be enjoyed from the bedroom or from the living room.
4. Living room, kitchen, laundry (closed) and dining room are in one open area.
Hopefully the design concept that I offer can be useful for you.
