Hi, I need a 4 star guesthouse hotel please.
I have 21 4 star places, can you tell me what area you would like to be in?
The North part of town, please.
There are quite a few.  If you'd like a cheap alternative, I can recommend Worth House, on Chesterton Road. Or for a moderate rate, Kirkwood House is next door.
Could you book the Kirkwood House for me for thursday, 6 people and 5 nights?
Your booking was successful. The reference number is 6G15LHZM. Is there anything else?
That is all I needed. Thanks.
Thank you, goodbye.
