I can see having one bedroom on the first floor, as it gives more flexibility: you could make it an office, or older people who don't like stairs could have it as a bedroom and have the upstairs for storage and a guest room. But I'd flip the bedroom and the bathroom/laundry: it makes the bathroom and laundry more accessible without going through the privacy of the bedroom, and gives the bedroom more room for windows (currently only one side of the building has windows, and there are none in the bathroom). Move the upstairs bath as well and it keeps all the plumbing in one section and splits the upstairs into two functional sections which could be separate bedrooms / office / storage / whatever.

Of course, that would mean that neither floor had an open floor plan so it could seem rather claustrophobic, especially with windows only down one side with neighbors right up next to the windows. The front window looks out right onto the parking slab and the high-power transmission lines running down the street. The best 'view' is out the back: that looks out onto some retaining ponds (potentially nice), and then there's a 4-lane road on the other side of the ponds. Except there are no windows out the back of the houses, so you're entirely missing out on the one potentially nice view. Yeah, I'd flip the bedroom and the bathroom/laundry, and I'd put windows looking out the back there - hell, maybe even a sliding door or something, make it easy to access your tiny backyard, have a cup of coffee out there or something.
