Could you please find me a 4 star guesthouse 
I found Acorn Guest House would that work for you?
Yes. Will you please make me a reservation?
Sure.  When will you check in and how long would you like to stay for?  Will it be just for yourself?
It's going to be for 8 people and 2 nights, starting Thursday.
I'm afraid that isn't available.  Could you book a different arrival day, or a shorter stay?
What about for just one night?
The booking is successful for 1 night. The reference number is NNA3OC5W. May I help you with anything else?
That is all! Thanks! 
It was my pleasure. Thank you for calling the Cambridge TownInfo Centre. Goodbye.
