U: I'm looking for a 4 star hotel in the south.

S: It looks like there aren't any 4-star hotels in the south.  Would you like me to search another area or look for different kind of hotel?

U: What about in the centre? A cheap 4 star hotel that includes free parking

S: It looks like if you wanted a hotel, you'd need to stay in the west part of town. There are guesthouses that meet your needs, though. Does that work?

U: So you are saying you have nothing south, 4 star and cheap that has free parking like I wanted?

S: sorry about that, actually rosa's bed and breakfast fits that criteria.

U: Is it known for being a quiet place to stay?
S: Rooms at Rosa's are extremely quiet. Would you like me to book a room for you, or do have additional questions?
