U: I'm looking for a guesthouse with free parking.

S: Do you have a preferred location or price range?

U: I'm not too concerned with location, but I would like it to include internet and have a 4 star rating please.

S: There are 16 guesthouses that meet those requirements. Any preference on price range?

U: Not really.  Anything would be fine.

S: I recommend the Acorn Guest House. Would you like a room there?

U: I want to stay in a large room, so can you check the room size first?
S: Acorn Guest House offers large rooms for their guests to enjoy during their stay.  Can I help you with anything else?
