I am looking for a place to stay. The hotel should include free wifi,
There are many hotels that match your criteria. Which area of town would you like to stay in?
area of town close to public transportation
Then, that narrows down to 3 hotels in the centre of town. Do you prefer expensive or moderate price range?
I'm not picky. It needs to have free parking, though.
Ashley hotel has free parking, would you like a reservation?
Oh, I'm sorry, I also want to make sure it's got a 4 star rating, at least. Could you confirm that for me please?
Unfortunately Ashley hotel is only 2 stars. There are no 4 star hotels from what I can see. Would you like me to search for 3 star hotels or 5 star?
Yes, can you search for a 5 star please?
I am sorry, there are not 5 stars available. 
Well, I'm not sure what I should so. I guess I should go with the two star place.
How about a three star hotel? I have two that would match your description.
Do you have any 4 star guesthouses available instead? 
Yes, the alexander bread and breakfast is a 4 star guesthouse in the centre. Would you like me to book you a room?
Yes, but only if they offer free parking. And free wifi. Do they?
Yes, both free wifi and parking is available at this location.
Thank you, could I get the postal code to this hotel, please?
The postcode is cb12de. Shall I book a room for you?
That is all I need for the time being. Thank you so much for the help.
Okay have a great day!
