i would like a hotel to stay in while i visit cambridge .
user
sure , what part of town do you prefer ?
assistant
we're visiting the south part of town , so let s stick with that area .
user
my favorite place in the south is the aylesbray lodge guest house . would you like me to book a room for you ?
assistant
i need it to be a 4 star guesthouse with free parking . does this fit our needs ?
user
aylesbray lodge guest house is a 4 star and is in the south of town
assistant
i actually only want a guesthouse if there is not a 4 star hotel with free parking available in the south
