U: I need to book a place to stay with a star of 4. I don't need free parking.

S: We have over 20 fine hotels. Do you have any preferences of cost or location?

U: I don't care about location, just would like a moderate price with 4 stars please.

S: We have 11 in the moderate range. They are all a guesthouse accommodation. Would you like one of these?

U: I need one with free wi-fi.

S: I have two: a and b guesthouse in the east and avalon in the north. Would one of these work for you?

U: Do you know which of A and B Guesthouse or Avalon has friendlier staff?
S: I don't have any information on Avalon and the A and B Guesthouse has mixed reviews. Some guests have really enjoyed the staff with one clerk making a hand drawn card for a guest's anniversary. There were others who were not treated professionally at all. Would you like to know more about either of them?
