I'm looking for a guest house that offers free parking.
I have located several guesthouses with free parking. Can you tell me the area you would like to stay in and the price range? That would help narrow our search.
Sure.  I would like it to be in the south and in the expensive price range.
I'm sorry, there are no matched in the South in that price range.  The South only has moderate and cheap. 
i will take a moderate guest house with parking then.
I would like to recommend aylesbray lodge guest house,would that be alright with you?
Yes, five people four nights, starting from Monday on. 
That wasn't available but I booked you at the Bridge Guest House.  It has everything you were looking for.  The reference number is 1AMM7M53.  
Thank you, that is all. 
Okay enjoy your stay.
