I need a hotel with a star of 4 that offers free wi-fi.   
There are three hotels that offer wifi and are 4-star. The Huntingdon Marriott Hotel, The Cambridge Belfry and University Arms Hotel. Would any of these suit your needs or do you need more information?
Which one is a moderate price range?
There are not any moderate priced hotels available. The Cambridge Belfry is inexpensive, while Huntington Marriott Hotel and University Arms Hotel are both expensive.
I think I'd prefer one of the expensive options. Which is your favorite?
I would recommend the Huntington Marriott Hotel, which is located in the west part of town at kingfisher way, hinchinbrook business park, huntingdon. Would you like to make a reservation?
No. I think I am all set. 
Great.  I hope you have a good day.
