I want to find a zero star rated hotel.
Interestingly enough, I have 3 of those! Do you have a certain area in mind? I have places in the north and centre.
It should be in the cheap price range
There is a guesthouse located in the north and a guesthouse located in the centre, do you have a preference of area?
I would prefer the centre please.
I have the el shaddai guesthouse.  Should I go ahead and book that now?
Yes can you please book that?
for how many people do i book and for how long?
Sorry, I actually won't need it booked after all. I only want to know if they have free parking and also the phone number and address there please.
Their address is 41 warkworth street, cb11eg. Their phone number is 01223327978. They do indeed have free parking.
Great, thank you so much! Now I just need to find a place to eat.
I have many different options for restaurants. Do you have a preference of the area, price range, or type of food?
Let's look for a cheap place. 
There are quite a few Chinese restaurants in that area. How about Golden House?
Sounds fine.  Could you make a reservation for 4 at 11:45 on Wednesday?  I will need the reference number too
I have made the reservation. Your reference number is FZT238P9. Is there anything else I can help you with?
No thank you that will be all. 
You are welcome, enjoy your stay in Cambridge.
