i am looking for a 4 star hotel in cambridge . it needs to include free parking .
{'service': 'hotel', 'act': 'request', 'slot_name': 'area', 'value': '?'} {'service': 'hotel', 'act': 'request', 'slot_name': 'price', 'value': '?'} {'service': 'hotel', 'act': 'inform', 'slot_name': 'choice', 'value': '19'}
i have 19 different options . is there an area or price range you prefer so that we can narrow it down ?
