I need a hotel or guest house in Cambridge please.
Sure, are you looking for anything specific?
I need a cheap hotel in the North side that has free parking and internet if available but not necessary.
I have no listings,can i check in another area?
What about one with free wifi?
Actually, since you said you did not mind a guesthouse earlier, I have something.  Worth House fits your criteria.  
Great.  Can I book that for three nights starting Monday for three people.  
Booking was successful. Reference number is : KPZGSMAA. Is there anything else I can help you with today? 
Great. That is all that I need today. Thanks!
You're welcome. Have a great day!
