There is no bedroom downstairs. The staircase is the small window to the right of the front door.
2 full baths are upstairs.
Please see my posts about the floorplan. I do think it is a Charleston, unfortunately no longer built by St Lawrence, the door at the top of the steps in the garage goes directly into the laundry room which is basically a galley with w and dryer on one side with no windows, goes into the kitchen. MT3K is correct, there are no downstairs bedrooms in Charleston. Hall bath behind wall that you see in photo that is very small and has no window. I will get back with more details as my husband gives them to me.
