U: I am looking for a 4 star guesthouse in Cambridge.

S: I have 18 results that match your request. To help narrow it down, what part of town would you like to stay in? Do you have a price range preference?

U: The hotel also needs to be cheap and have free wifi.

S: There are 7 hotels that meet that criteria. Do you have an area preference?

U: Do any of these 7 have free wifi?

S: They all have free wifi.

U: Any of them will do.  I'll book a room in whichever one you think is best.

S: The alexander bed and breakfast is in the center of town, would you like help with the booking?

U: Can you first tell me whether the Alexander Bed and Breakfast has any cooking facilities for guests to use?

S: There are no kitchens accessible for guests. Are you still interested despite this?

U: Well, do you have to be a certain age or anything to book?

S: You need to be at least 18 years old to check in. Would you like to book a room?

U: I'd also like to know if they have wifi access at the hotel?
S: Sure, let me check that out for you. Yes, free Wi-Fi access is available for you at no extra cost at Alexander Bed and Breakfast.
