Task-oriented dialogue about: hotel

I need a guesthouse please.
There are 24 different guesthouses available. Is there a particular area of the city you would like to stay in?
I would like to stay in the North area.
There are 5 option in the north. Do you have any other preferences to help narrow down your choice?
I am actually looking for a 4 star rating in an expensive price range.
I have several hotels available with a 4 star rating but none in an expensive price range. Would a moderate range work for you?
Is sure would. Can you book a room for 2 people for 2 nights on Monday?
I booked for you a room at arbury lodge guesthouse. It has parking slots and free wifi. Do you need anything else?
I need a reference number for that booking!
Sure, your reference number is B1IP09IZ .
Wonderful! Good bye!
Glad I could help! Goodbye.
