U: Yes, hi. Would you be able to suggest a reasonably priced guesthouse for our stay in Cambridge?

S: I'd be happy to help you. There are 24 guesthouses to choose from. Is there an area you'd like to stay in, or perhaps a certain price range?

U: Well, how about a moderate price range and a star rating of zero?  Oh, and I don't need free parking.

S: I'm sorry, I haven't found a guesthouse that meets those requirements.  Could you possibly stay at a higher rated place, or try a hotel room?

U: Please show me a guesthouse with the lowest available rating.

S: The alpha-milton guest house is in the north with 3 stars, but there's no wifi nor parking. Will that suffice for you?

U: Yes that will work. I'll need the area, postcode and address, please.

S: The Alpha-Milton Guest House is in the north part of town at 63 Milton Road. Their postcode is cb41xa. Need anything else?

U: I really want a place that is located in a good area. Do you think this guest house does?
S: Yes, the Alpha-Milton Guest House is considered to be in a perfect location within walking distance to public transportation and a lot of attractions.
