U: Hi. I am looking for a hotel that is a guesthouse that has free parking. Can you help me find one?

S: There are 21 options available. Do you have any other preferences to narrow down the search?

U: Sure, how about an expensive, four star guest house?

S: It doesn't look like we have any expensive 4 star guesthouses. There are some which are moderate if you are interested.

U: Moderate will do. Can you give me more information please?

S: The Archway House is very nice. Would you like me to book a reservation?

U: Do the rooms have supportive mattresses for guests with back problems?
S: There are mixed reviews when it comes to the beds. Some say it's too soft or hard while some say they liked the comfort of the bed. Would you like me to see if they can provide a mattress for your needs?
