user: I want to know about 4 star hotels that include free parking for guests.

assistant: What area of town would you like to stay in?

user: It doesn't matter but it should be a guesthouse.

assistant: There are about 16 choices. Maybe we can narrow it down if you tell me what price range you were looking at?

user: guesthouses not hotel, sorry can you suggest one and give me their phone number please

assistant: I have 33 guesthouses all over town ranging from cheap to moderate. What area do you prefer and which price range will work for you.

user: As long as it's a guesthouse with 4 stars and free parking I will be happy. Which one do you recommend?

assistant: There are 16 all over town, that meet your criteria. If you could tell me which part of town you would prefer, that would help narrow the choices down.

user: Please give me the phone number of a guesthouse, it doesn't matter where it is, as long as it has parking and 4 stars.
