I am needing to find a place to stay while traveling in Cambridge. I would like a guesthouse that is 4 stars.
I have results for 5 guesthouses, which part of town are you looking to stay in, and do you need parking?
I don't care about the part of town, but I do want free parking.
I have found 16 guesthouse style hotels. Is there a specific area you would like or price range?
Like I said I needed a guesthouse with 4 stars... Location and price don't matter.
The acorn guest house meets your criteria. Would you like to book a room?
Please do. It will be a 3 night stay for 4 people.
What day would you like to start your stay?
On wednesday please
Okay, I've booked that for you.  Your reference number is 5X06NQ04.
I am also hoping to find a place to eat in the centre that isn't too expensive. Do you have any suggestions for modern european food? 
There are 2 restaurants in the moderate price range, and 1 that is cheap. Which pricing is preferable to you?
Give me the postcode, phone number and address of one of the moderately priced ones
De Luca Cuccina and Bar is located at 83 Regent Street, cb21aw and the phone number is 01223356666. Is there anything else I can help you with?
Perfect! That's all I need, thank you. 
You are welcome. I hope you enjoy your stay.
