user: I am looking for places to visit in downtown Cambridge. What are some popular attractions?

assistant: There is architecture, boats, colleges, museums, and many other things.

user: Recommend something that's in the center of town for me.

assistant: 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?

user: I'm also looking for a place to stay.

assistant: What area would you like to stay in?

user: I want to stay in the center of town in a 0 star hotel that is moderately priced and has free parking.

assistant: 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?

user: Free parking would be nice but it is not a necessity.

assistant: 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?

user: Yes please. I'll need to for 8 people for 4 nights starting Wednesday

assistant: Done! Your reference number is 07Z05P6U . Do you need anything else?

user: Yes, I also need a taxi from the hotel at 16:30.

assistant: I have booked your taxi. Be expecting a red Honda. Their phone number is 07543221637.

user: That will be all for today. Thanks. Goodbye.

assistant: Thank you for using our system today!
