Room 22 is empty, but as a single with a double-bed it's also one of the more expensive rooms and it's not really out of the way. Otherwise there's the dorms, which are much cheaper and could have been where Midii was staying in the past. Seventeen is out of the way and has a kedanese family with a couple of kidlets who could be good room-mates for her.

Does Midii have a job? If so Anton will just charge her as usual with his other patrons.
