now like I would do it ;).
Basement ... utility room towards the street .. and you can already see the staircase has moved.
On the ground floor, an entrance area with a wardrobe cabinet, WC above the utility room, small decorative niche and partition wall to the living area with glass sliding door
Kitchen with the cooktop row in the tall cabinet wall and a nice preparation island. Tall cabinets from the left .. raised dishwasher, then cooktop space, then oven tall cabinet and finally refrigerator. In the corner on the right possibly a custom solution for decoration or rarely used items.
Then a seating area with a modern kitchen sofa and kitchen armchair, table approx. 100x150 cm, TV bottom right in the corner.
I would make the terrace access wider than 176 cm, otherwise the sliding door will not work well.
And then the upper floor:
Bathroom again above the utility room .. shower tiled flush in the corner with a partition wall and divided glass door, which also opens inward primarily so that the area in front of the shower does not get wet.
Additionally WC, dresser under the window, wide washbasin, possibly an integrated washer-dryer here (then you don’t have to carry laundry from the upper floor to the basement and back).
Bottom of the plan the "master bedroom" with a bed of 150x210, i.e. mattress 140x200 plus bed frame. 200 cm closet adapted under the slant.
Guest room ... I just noticed, possibly better a sliding door, then the bed and a 40 cm deep closet can hopefully fit better in the room.
In the anteroom on the wall to the bathroom some storage .. window as a seating window and above plan top another dresser under the window sill.
