U: Hello, I am looking for a place to stay in Cambridge.

S: I can help with that. Do you have an area of town, or a price range in mind?

U: I'm not picky about the area of town or the price, but I absolutely need free wifi!

S: Ok, almost all of the hotels have free wifi, do you have a star rating you would like?

U: I don't care.

S: There are 32 hotels that have free wifi. Do you have any preference of price range or area, or should I choose one for you?

U: I would like a guesthouse type but the price range is not as important.

S: How about the moderately priced Rosa's Bed and Breakfast? I also have 22 other entries, if you would prefer something else.

U: How clean are their rooms?
S: The housekeepers do an exceptional job at Rosa's Bed and Breakfast. Should I make a reservation for you?
