U: I am needing to find a place to stay while traveling in Cambridge. I would like a guesthouse that is 4 stars.

S: I have results for 5 guesthouses, which part of town are you looking to stay in, and do you need parking?

U: I don't care about the part of town, but I do want free parking.

S: I have found 16 guesthouse style hotels. Is there a specific area you would like or price range?

U: Like I said I needed a guesthouse with 4 stars... Location and price don't matter.

S: The acorn guest house meets your criteria. Would you like to book a room?

U: I need to make sure that this location is very peaceful and quiet.
S: According to the reviews I have on hand for that location, the location is quiet, conducive to conversation, and lacking in disruptive patrons.
