There are lots of places to choose from. Are you looking for something in a specific area of town?
I need a place to stay, and I need it to provide free parking. No, but I'd like something with 4-star quality.

{"__type": "Inform", "entity": {"__type": "Hotel", "choice": "19"}} {"__type": "Request", "service": "hotel", "values": ["area", "price range"]}
That narrows it down to 19 places to stay. I'll need to know what part of town you want to stay in or your pricerange to better help you.
