I am looking for a gueshouse to stay in during my visit. I would like for it to be in the east section of town.
There are six entries, do you have any other preferences in hotel choice?
I'd like a 4 star place that's on the pricier side.
There are no 4 star expensive guesthouses on the East side of town. Would you be interested in a cheap or moderately priced one instead?
I would like one that is cheap then.
Autumn house is cheap and has free internet and parking. Would you like me to book a reservation for you?
Yes please. Can you book the reservation for Saturday for 5 guests for a 2 night stay. Thanks. 
Sorry, there are no rooms available for your specifications. Do you want to try a different day or a shorter stay?
Try for 1 night instead. If that works, can I have the reference number?
How about the Autumn House for 1 night starting Saturday and your reference number is SVCIWLWA.
I also need to find something called gonville and caius college, can you help?
Gonville and Caius College is located in the center of town on Trinity Street. Anything else I can do for you?
Can I get the postcode?
No problem, the postal code is cb21ta.  Did you need the phone number as well?
No thanks - I'm all set. Thank you for your help today.
You are welcome. Have a pleasant stay.
