I'll try to say something about the last drafts (p. 7 for the ground floor, as far as I found it): My favorite question (from my own experience in a rental apartment) is always about the walking routes. Are the walking routes in a floor plan practical? Or will they become annoying at some point?
Compared to the first draft (p. 1), I already find it good that these two doors standing close together (kitchen/dining area) are gone.
However: One of the most frequent routes will be from the living/dining area to the toilet on the ground floor. That is relatively far. With guests who haven't been there often yet, you can already expect that they might end up in the utility room or the storage room under the stairs. Yes, I also read this requirement "not adjacent to the living room," but... I don't know if you are doing yourself a favor with that requirement.
If you don't want to change the upper floor and don't want to unnecessarily complicate the pipework (i.e., don't want to move the utility room), there are hardly any good solutions. Possibly, one could (it may be that there is not enough space for this) place the ground floor WC between the utility room and the kitchen. If that fits, it would be the best solution in terms of walking routes: closest door to the living area, straight line to the guest room. No circulation pipe necessary (all wet rooms are adjacent to the utility room). Also easily accessible if you come in from outside with urgent washing needs, without the ground floor WC being directly in the dirty area. (By the way, the stairs are located in the dirty area—there are many who rather don’t like that.)
But it may be that there is not enough space for that. Then, in terms of walking routes, the suggestion from ypg on page 5 would still be more straightforward (straight walking route once you are in the hallway).
If that also doesn’t work because it has been decided "WC not adjacent to living room," then I would puzzle with the rooms down there again and see how to get a good walking route. For most people I know, the WC on the ground floor is actually used more often than the WCs upstairs.
