You are missing the toilet. Unless you consider her to have an outhouse even when she has an upstairs bathroom - which I think unlikely in itself if there is no plumbing. Even the richest people are not inclined to let their servants haul lots of hot water upstairs from the kitchen, if it is only because it means additional waiting time and chances for accidents. In all the old houses I've seen and partially lived in, even up to the middle of this century, the bathrooms are all downstairs next to the kitchen.

Pet peeve of mine

Otherwise I like it a lot.
