I live in a small brickhouse which had been a garment factory before. It's build in 1901 and our guest room is also my handicraft room.
I make a good price but I expect you to change the sheets before you leave. Also who ever lived in a house knows, you can never get it scrupulously clean - I do my best, but please don't fuzz over dust you found but I didn't.
You have a private toilet but washing facilities are upstaires. Of course you are also very welcome there to take a shower.
