i am looking for a place to stay . the hotel should be in the cheap price range and should be in the north
{'service': 'hotel', 'act': 'select', 'slot_name': 'none', 'value': 'none'} {'service': 'hotel', 'act': 'inform', 'slot_name': 'stars', 'value': '0'} {'service': 'hotel', 'act': 'inform', 'slot_name': 'stars', 'value': '4'}
okay . there is a 0 star place , and a 4 star place . which do you prefer ?
