Can you help me find a place to stay? I am looking for an expensive hotel, but it doesn't need free parking.
Unfortunately there are no hotels available that fit that criteria. 
What can you recommend? And please I need free wifi.
There are 5 expensive hotels with free parking. I recommend The Gonville Hotel which has a 3 star rating.
Does it have free wifi? Is it in the north?
It does have free wifi, but it is located in the centre, there are no expensive hotels in the north area.
Check for one in the moderate price range with that criteria. Book something for 1 person for 4 nights starting on monday. 
Would you prefer a hotel or a guesthouse?
