U: I need a place to stay in Cambridge that includes free wifi. I don't need free parking.

S: Would you like to try cityroomz?  I can book it for you?

U: Is it in the West? what is the price range?

S: Cityroomz is moderately priced and in the centre. Are you open to places that offer free parking, or do you specifically want to avoid it?

U: I'm open to it, and I suppose the centre will do. But I'd prefer the west side if there is one.

S: I'm so sorry.  There are no hotels on the west side that match your requests.

U: Could you tell me if the employees are friendly and helpful?
S: Yes, the employees at Cityroomz do appear to be friendly and helpful. Past guests have said they are kind, and made them feel very welcome.
