I'm looking for a museum in town
There are 23 museums in Cambridge. Any particular one or area you are looking for?
I'd like to visit one with a low or free entrance fee. I also need to know in what area the museum is located.
I can recommend Broughton House Gallery. It is free and in the centre of town.
Is the Broughton House Gallery a museum? I am also looking for a place to stay. Preferably in the north.
Yes it is a museum. There are many hotels that match your criteria. Do you need free wifi or parking?
I do not need to have free parking or wifi. Please check to see if there is a guesthouse available instead of a hotel for our stay. 
There are 11 guesthouses in the north. Do you have a price range or number of stars in mind?
I would like it to be at least $100 a night and 3 stars.
I have two available guesthouses. They are both moderately priced. The Alpha-Milton and the Hamilton Lodge. Would you like more info on one of those?
Does one of those offer free parking? I would like it to have that where I stay. 
The Hamilton Lodge has free parking and internet as well.  I can try to book it once I know the day, length of stay, and how many people.
Great. Could I get the postcode, phone number, and address please?
The postcode is cb41da and the phone is 01223365664. Hamilton Lodge is located at 156 Chesterton Road. Anything else I can help you with?
No, I think that is All. Thank you.
You're welcome. Enjoy your time in Cambridge!
