Guten Tag, I am staying overnight in Cambridge and need a place to sleep. I need free parking and internet.
I have 4 different options for you. I have two cheaper guesthouses and two expensive hotels. Do you have a preference? 
No, but I'd really like to be on the south end of the city. Do any of those fit the bill?
Sure.  Does price matter?  We can narrow it down and find exactly what you need.
No I don't care about the price. Which one do you recommend?
I would recommend aylesbray lodge guest house. Would you like me to book that for you?
Yes, book it for 4 people and 4 nights starting from tuesday.
The booking was unsuccessful. would you like another day or a shorter stay?
How about for 3 nights?
Booked! Reference number is: 84ESP6F5
Great.  I am all set then.  Have a nice day.  Bye.
Have a nice stay.  Bye.
