Task-oriented dialogue about: hotel

Hi, I'm looking for a place to stay with free parking and zero stars.
I have 2. City centre north b and b in the north and the el shaddai in the centre. Which one would you prefer?
the el shaddai in the centre
Ok no problem, when would you like the room booked for?
I need it for four people and four nights starting Monday.
Booking was unsuccessful. Want to find another hotel?
Lets try City centre north b and b, if that is not successful, any hotel in the same price range
The A and B was indeed successful and your reference number is II677Z30 .
Thank you so much for your help. Have a nice day. Bye.
You are very welcome. Thank you for contacting the Cambridge TownInfo centre. Good bye.
