I'm looking for a moderately priced hotel that offers free wifi. Do you have any of those?
I have several options that meet your criteria. One is in the centre with 0 stars, two in the north with 2 stars.
I am sorry I am actually looking for a 4 star hotel with free parking. Is there any available?
I have not hotels matching your criteria.
Can you locate me a 3 star hotel with parking.
I'm sorry, but I am still not pulling any matches up. 
Could you check again? A moderate priced, 4 star hotel or guesthouse, that offers free wifi and parking.
none in our list. can you change location?
Are there any 4 star hotels or guesthouses with free parking and wifi in a different price range?
