Hello , I 'm looking for a 1 star hotel with free parking in the west .

We do n't have any hotels that meet those specifications .   Would you like a different area , or perhaps a different star rating ?
inform((_:search,stars,'4');(_:search,type,'Hotel'))
user
Can we try a 4 star rating instead ?
