I need a place to stay in the centre of cambridge.
do you have any constraints regarding cost or quality?
I am looking fro something cheap with a 0 star rating.
How does El Shaddai sound? It is a cheap guesthouse with 0 stars located centrally. It includes both free wifi and free parking?
I would like to book a hotel.
There are no cheap hotels with 0 stars in the centre. Would you like to book cityroomz? It is a hotel that has 0 stars and it is moderately priced.
Cityroomz will be fine. I need a room for 2 nights starting Thursday. There will be a total of 8 guests.
I'm sorry, the book was unsuccessful.  Would you like to try for another date or a shorter stay?
How about for only a one night stay?
Sadly I couldn't book Cityroomz. But I was able to book Alexander Bed and Breakfast a 4 star guesthouse for an even cheaper rate for one night with 8 guests. 
Thank you! What is the reference number? 
Your reference number is 6MYWN42P.
I would also like to know about fun things to do in town. What types of entertainment is available near the hotel?
There is no entertainment in the centre would you like to look for another type of attraction?
In that case can you tell me the address of some of the colleges in the area?
We have Gonville and Caius College on Trinity Street, Emmanuel College on Saint Andrew's Street, and Downing College on Regent Street.
Can you give me the full address for Downing College please?
Downing College is on Regent Street with the postal code cb21dq. Would you like the phone number?
No thanks, but I'd like to book a taxi between the two locations, please.
Okay, when would you like to leave or arrive by?
I want to leave my hotel no later than 17:15.
