Thank you. I'm also looking for a place to stay. I'd like a guest house that's expensive with a star of 4. 
I'm sorry there aren't any matches. Would you like to try something in the moderate price range?
How about  a cheap place instead?
There are 7 choices in the cheap price range, are there any preferences?
are there any guesthouses?
Yes, there are several. Do you have a certain area in mind?
The area is not an issue. I do want it to be an actual hotel. 
There is one cheap hotel in the west. It is the Cambridge Belfry. Would you like me to book it for you?
Yes thank you. I need a room for 7 people and 5 nights starting from Wednesday.
I will work on getting that booked for you.
