I am looking for a hotel to stay at in Cambridge, at least a 4 star place please
I've found 3 total entries for what you're searching for. The hotels are all 4 stars and ranges from cheap to expensive. It can be filtered down more to include prices.
are any of them on the north side of town?
No, sorry. Would you like me to try searching for something else?
Can you check the north side for other hotels? 
Yes I can search for other hotels, do you want to change the star from 4?
i'd prefer a 4 star in the north
I'm sorry there are still no matching results. I can try a different part of town if you would like. 
Is there possibly a guest house?  I need free parking also.
There are a number of guesthouses in that area with 4 stars. Do you have a price preference?
