I would like to visit a college in the centre of town.
There are 13 colleges in the center, but I would recommend christ's college. It's at saint andrew's street, postcode cb23bu, phone number 01223334900, and the entrance fee is free!
Thank you very much for your help.
Is there anything else I can assist you with today?
Yes, can you help me locate a guesthouse that stay in that is also in the centre of town?
I have two, in the cheap range. Are there any other criteria you would like me to narrow it by?
Yeah, I'd like someplace with free wifi, please.
I have found 2 guesthouses that are in the cheap range. One has 0 stars and the other has 4 stars. Would you like for me to reserve one for you?
I need the postcode too. 
The Alexander Bed and Breakfast has a postcode of cb12de. El Shaddai guesthouse has a postcode of cb11eg. Anything else I can provide? 
I also need to take a taxi between the college and the guesthouse. Can you help me with that?
When do you wan to leave or arrive by?
I want to leave christ's college by 6:30.
Alright, I've got you booked in a blue Volkswagen.
Can you tell me the contact number for the taxi please?
The number is 07841875956, is that all you need?
Yes it is, thank you for your help.
