I would like to stay at a guesthouse while I'm in cambridge. It doesn't need to have internet. 
I'd recommend alpha-milton guest house in the north. It's a moderately priced three star hotel. Would you like a room?
No thanks - not yet.  Does it have free parking?
Unfortunately it does not have free parking. What price range do you have in mind? I can find you one that does have parking
I don't have any price range in mind, I just want a guesthouse with free parking on the north side
I would then recommend the acorn guest house, a moderately priced 4 star guesthouse located at 154 chesterton road. Would you like to book a room?
Yes, I do need to book a room.
How many people will be joining you, if any?  
Actually, I'll book later. Can you help me find a train though?
Where do you want to travel to and from?
