i want a place to stay in Cambridge the is moderate price no wifi
Sure.  Would you like a particular area of town? 
An inexpensive area with free parking if possible. 
Okay, I recommend the Acorn Guest House. It's located in the north. Would you like me to book a reservation for you?
Sure!  I would like that!
I just need to know for what day, how many nights and how many guests for the reservation.
I need a reservation for 5 people and 5 nights starting Wednesday. Thanks! 
Done! Your reference number is PMWGUS04. Can I help you with anything else?
No thanks, that's all I needed.  I appreciate your help!
I'm happy we could be of service. Enjoy your stay in Cambridge!
