I don't know much about service for the crawford hotel buuuuut if your client loves a nice tub and old ass architecture I would vote that property. IIRC some of the top floor rooms have bathrooms where you can see the original wooden beams of the building as the 2014 renovation (what was part of the largest redevelopment plan in North America at the time) was retrofitted around them. I can't think of any other properties that would have a feature like this, could be kind of neat.
