U: I'm just looking for a place to sleep tonight in Cambridge.

S: Sure, there are 33 hotels available. Do you have any other criteria?

U: Could it be in the north and include free wifi please?

S: There are several places to stay in the north that offer free internet.  do you have a preference of stars and price range?

U: No. But it should be a guesthouse.

S: There are several in the moderate price range and 1 in the cheap range, do you have a preference?

U: I would like a guesthouse in the moderate price range for one person and four nights, starting on Sunday.

S: There are several options, but I would definitely recommend the limehouse. If that sounds good, I can book it for you.

U: How is the cleaning rating for the hotel?
S: Some past guests at the Limehouse say that the rooms were very clean, while some guests say that the rooms were not clean.
