Can you help me find a guesthouse that offers free wifi?
I sure can.  There are 23 guesthouse with free wifi.  Would you prefer a certain part of town?
I'd love something in the east, hopefully with free parking.
Okay, there are 5 options. Do you have a price range in mind?
I would like to stay in a hotel, not a guesthouse. 
Sounds like you are looking for express by holiday inn cambridge.  Can I reserve a room for you?
Yes please book that for 2 people and 4 nights starting from Tuesday. I will also need the reference number.
The booking was successful and reference number is ZDG5KJ7S. Is there anything else I can assist with?
No that is all for now. Thank you!
You're welcome and enjoy your visit.
