Task-oriented dialogue about: hotel

Hello! I'm looking for a place to stay with free parking and zero stars.
Yes, I have two guesthouses that fit that criteria. Would you like to stay in the north or centre?
Do you have anything in the east?
There is nothing in the east with zero stars and free parking. Do you want to change the star rating or other criteria?
No can you please check in the north instead then?
The city centre north b and b meets your criteria. Do you want to make a reservation?
Yes, I would like to make a reservation on Saturday for 6 people and we will be staying for 2 nights.
Unfortunately the booking was unsuccessful, would you like to try another hotel?
Yes i would like something in the same pricerange.
Nothing else is available on the cheap side. Something else perhaps? I am sorry.
You can change any other criteria, but the price range should be the same as the city centre north b and b. Please try again.
