From the front door, I'd put the stairs on the left (alongside the front wall, turning back towards the center of the house, in line with the window about halfway up the side. Stairs to the side door leading downward underneath the upper part of the staircase. Kitchen in back left corner of the house, dining room back right corner. Living room front left corner, with the double windows overlooking the porch.
Upstairs, bathroom back left side (where the small window is), and three bedrooms, roughly centered on each of the double windows. Make one bedroom larger (the master bedroom), and probably situated in front. You could play with closet placement a little.
If the home has an exterior chimney (one that goes up the wall on the outside), then that could help determine either kitchen or living room placement (and perhaps master bedroom placement), provided the house is old enough.
I wouldn't go crazy with a modern floor plan (one that has a larger kitchen or first floor bath/half bath or more closets) because most older houses I've seen were quartered on each floor (meaning 4 "rooms" per floor). Bathrooms are expensive and require extra plumbing and usually another window for ventilation. Some area municipalities taxed home owners on the number of rooms they had (and counted closets as rooms), so armoires and chiffarobes (sp?) were more common. Also, we didn't have as much junk as we do now.
