I'm looking for a cheap place to stay. Can you help?
I have a number of cheap hotels available; do you want to stay in a particular area of town?
I don't care which area the hotel is in.
Ok, would you prefer a guesthouse or a hotel?

I'm sorry I don't have any matches. Do you want me to check a different price range?
Yes, please try expensive.
I'm sorry, there's not guesthouse fitting THAT description either.  Do you want to try a different hotel type or something?
