Task-oriented dialogue about: hotel

I would like to know more about Rosa's b&b
Sure Rosa's is located on the south side of town, is in the cheap price range and is rated 4 stars.
Okay great. Can you book me a room for 7 people and 3 nights starting from saturday?
I'm sorry Rosa's does not have rooms available for those days. Would you like to try a different hotel?
Yes, do you have a different cheap hotel available?
I have none in the same area, would a different are be okay?
Just please can you find a place in the same price range. I'll need a reference number please.
