That is not possible. They were lying to you. You can't see the other's review until you post your review or the review window expires. You can never change your review once posted (though you can comment on a review someone else left).

They were very pushy about asking "are you going to give me 5 stars?" before/during the stay, and saying things like "my business depends on 5 star ratings". Obviously there are lots of paths out of that situation that don't involve someone giving them 5 stars, but I'm sure it works on people.

Edit: it did not work on me
