I would welcome your comments on that cabin when you return.  I had one booked but decided to cancel.  I’ve never sailed in an inside cabin let alone one that is the size of a large closet at 103 square feet.  If you look at several of the Silhouette cruises, these cabins are usually open for booking.  The mid ship location on deck nine along with the pricing are positives but I personally couldn’t deal with the potential claustrophobia.  Good luck and happy sailing!
