i am looking for a place to stay. The hotel should be in the type of hotel and should have a star of 4.
You have three options: The Cambridge Belfry, which is inexpensive, the Huntingdon Marriott, which is expensive, both in the west, or University Arms, an expensive hotel in the centre.
do any of them have free wifi ?
All three of them offer both free parking and free wifi. Did you prefer the west or centre?
I really don't care you choose
I recommend the University Arms Hotel, on Regent Street in the city centre.  Would you like me to book it for you?
Could I have the  area and postcode.
As I said, University Arms Hotel is in the centre. It's postcode is cb21ad. Would you like a room?
No thanks. I do need the area and address of Ballare please, minus the attitude. 
My apologies. The Ballare is at heidelberg garders, lion yard cb23na. Their phone number is 01223364222
That should be all I need. Thank you for your help.
We hope you have a pleasant stay!
