Am I required to say how long I booked for? And her prices are displayed on her profile.
Yes you are required to say how long you booked for, not much point to a review unless we know what services were provided within a given amount of time. As far as prices go the ones shown on her profile are subject to change, the price you paid for your booking never will.
There's a useful guide to review writing and the summary shows the information required.
