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

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

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

assistant: 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?

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

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

user: That's okay, Cityroomz will work. Can you book it for 3 people for 2 nights starting on Tuesday?
