U: Hello I'll be coming to Cambridge and need a room to stay in. Can you recommend a guesthouse that has free parking?

S: I have 21 guesthouses in cambridge.  What price range and what area were you looking for?

U: I don't have a price range in mind. But I would like a 4 star rating and somewhere that offers free parking.

S: Ok, there are 16 hotels that meet that criteria. Is there a particular area of town you're interested in?

U: No I don't care which area it is in, just so it is a guesthouse with free parking and 4 stars.

S: The Alexander Bed and Breakfast is a popular choice. It's inexpensive, but rated 4 stars, and offers both free parking and free wifi.

U: Does this place have a friendly staff?
S: Alexander Bed and Breakfast according to past guests has friendly staff.  Would you like me to reserve a room for you?
