I am looking for a hotel called finches bed and breakfast. 
Finches Bed and Breakfast is a guesthouse on the west side of town and falls in the cheap price range. Are you interested in booking a room there?
Yes I am, I need a reservation for 6 people for 3 nights starting on Wednesday.
Unfortunately, I was unable to make the reservation. Would you like to try for another arrival date or a shorter stay?
Is there anything open for just 1 night?
Sure.  Your reference number is ZELLMALY.
Great, that's all I need today. Thank you for your help!
We're always happy to help, and I hope you enjoy your stay in Cambridge!
