I vote for a large area in the basement. Who wants to enter the building through the laundry room? I certainly don't want that when I come home, and I love laundry! My laundry (washers, sink, etc.) are in the basement and I don't find it inconvenient, in the least. My dryers, ironing tackle and sewing room are on the first floor however. I dry out of doors all most all the time so the "drying room" gets used mostly for sorting, folding, ironing etc. It's wonderful to have a waystation for all the textiles that keeps them out of the living area. Laundry, for me, always involves sorting and baskets of "in process" items which I wouldn't want standing around in my upstairs hallways, my entrance room or mudroom. I'd much rather have it out of sight. If I lived in a modern house with a dry finished basement, I would combine the washing room with the dryer room with ironing and sewing thrown in located in the basement. But my house is very old (c1840) and the basement would never be suitable for ironing or drying space, so I content myself with keeping only the washers there, in a space I have combined with my flower arranging workroom and my household utility sinks in the same section of the basement. That way combines all the plumbing needs economically. Molly~

I like weedys's idea of putting the laundry where the master toilet was, recessing the door to the master bedroom to allow for a door into the new laundry, and then sorting out your master bathroom and closet space because all you're doing there is swapping floor space. You don't have to deal with exterior walls and window locations. I'll toss this idea out. Move the laundry over to where the linen closet was and move the linen closet across so it backs up to the stairway. Bedroom closets go behind the laundry. You could also move the kids' bathroom to where I have the new laundry. With the bathroom layout adjusted of course. Then move the washer and dryer to where the tub is in the old kid's bathroom. In that laundry you could even keep the toilet and sink for a laundry/half-bath.

Maybe the OP can decide what size machines suit his/ her laundry room ;-) One of those Whirlpool machines costs more than the Miele, and both cost more than the Miele which comes to the market next month. I’m not advocating any particular brand, but the other significant advantage for the Miele in an older house is that it does not require a 220v receptacle, which every other electric dryer will. That’s another savings. An old house with stone walls and a slate roof is not without its challenges when it comes to adding amenities. That’s where I do think this particular appliance could make a lot of sense for you. Good luck!

Maybe do the 2 bedrooms with carpet and then just match the othere 2 spaces with the same tile. I think trying to match and miss the laminate would be worse.
