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: Does the acorn offer rooms with comfortable beds?
S: According to the reviews I have on hand for this location, the opinions are mostly negative.  Only one quarter found them to be comfortable, while three quarters found them uncomfortable, poor quality, and a source of back aches.
