Did you mention anything about the 150 pounds in your review?
IMHO, "complaining about price" in any arguable fashion seems to be reason enough to get something removed.
If you would have said "I really disliked their checkin process", the review would probably stand.
I have done consulting for an extreme micro-manager of a small business who was on the phone to trip advisor with every single negative review she received. The only time she was ever able to get a review removed was if it mentioned her prices in some fashion.
