I am looking for a place to stay. The hotel should be in the type of guesthouse and should be in the cheap price range
There are 9 cheap guesthouses in Cambridge.  To help narrow it down, is there a part of town you prefer?
Not really. I'd like a 4 star guesthouse, though, is that possible? 
There are seven that fit. Might I suggest the alexander bed and breakfast?
I think I have heard of that.  Can you just get me an address?
Absolutely! The Alexander Bed and Breakfast is located at 56 Saint Barnabas Road. Would you like me to book your stay?
No. I do need some options for Entertainment sort of attractions. In the centre of town. 
I have many ideas such as architecture, museums, theaters etc. Do you have a preference?
Museums or theaters, thank you.
I recommend the Broughton House Gallery. Would you like more information?
Actually, what colleges do you recommend?
Downing College looks nice, do you need to know anything else?
Could you give me the phone number and address for Downing College please?
The phone number is 01223334860. The address is regent street, post code cb21dq. May I help with anything else?
No, that will be all, thanks.
Thank you for contacting us and have a nice day.
