I am looking for places to visit in downtown Cambridge. What are some popular attractions?
There is architecture, boats, colleges, museums, and many other things.
Recommend something that's in the center of town for me.
The Cambridge Contemporary Art museum is a fantastic place to visit. It's located at 6 Trinity Street and admission is free! Do you need more information?
I'm also looking for a place to stay.
What area would you like to stay in?
I want to stay in the center of town in a 0 star hotel that is moderately priced and has free parking.
There's not an exact match to fit your needs. There's a hotel without free parking available. Or, if you need the free parking, would a cheap guesthouse work instead?
Free parking would be nice but it is not a necessity.
Okay, if the lack of parking isn't a dealbreaker, you might enjoy cityroomz. Their number is 01223304050. Shall I book a room for you?
Yes please. I'll need to for 8 people for 4 nights starting Wednesday
Done! Your reference number is 07Z05P6U. Do you need anything else?
Yes, I also need a taxi from the hotel at 16:30.
I have booked your taxi. Be expecting a red Honda. Their phone number is 07543221637. 
That will be all for today. Thanks. Goodbye.
