U: Yes I would like to stay in a guesthouse that is moderately priced.

S: Sure, acorn guest house has 4 stars, would you like me to book it?

U: I need a place in the north, with free wifi.

S: You have about 8 places that would fit your criteria. Almost all are 4 star rated. If you don't mind a recommendation, the Limehouse is known as one of the best.

U: Is the wifi free or does it cost extra there?
S: Yes, there is an extra fee to access the WiFi at Limehouse. Are there any other questions that I can help you with today?
