user: Hi, I would like to find a place to stay in Cambridge with free wifi.

assistant: I have several different options. In order to narrow them down, is there a certain price rang you would prefer?

user: In the moderate price range please. Oh and it needs to be a guesthouse.

assistant: Alright, I have found 14 recommendations. Do you know what area you would prefer to stay in?

user: The area doesn't matter, but I need to know if they have free parking.

assistant: I'm sorry, but I'm running into some errors in my system. Could you please restate your hotel requirements?

user: I'm looking for a place to stay- a guesthouse. It needs to be in the moderate price range and needs to have free wifi.

assistant: I have the a and b guest house and it does have free internet. Would you like to book this?

user: Could you tell me what area it is in and whether it has free parking?

assistant: The A & B Guesthouse does not have free parking.

user: I also need a train for Friday departing from Ely to Cambridge for 5 people and arriving by 16:30. Can you book this and get a reference number for me?

assistant: The closest match for you would be the TR4389. You'll depart at 15:35 and arrive at 15:52. Reference number D40MV6A4 . 22 GBP payable at the station.

user: Great thank you for your help today.
