In order to replace the carpet in the front cabin of our Contessa, all of the wood furniture ( there is a small cabinet up front, under the dash, a magazine rack beside the passenger seat, and a larger cabinet behind the passenger seat) had to come out. finding one of the screws was tricky, but once found, removal was quick and done with no damage to the woodwork, so it all went back in looking great. The whole job, from start to finish, took about 8 hours, of which less than one hour was to remove and refit the wood furniture. I haven't started on the bedroom, which doesn't look as easy. There, I may cut around the tables on each side of the bed rather than chance breaking something trying to get them out.
I also removed the front of the TV cabinet. It has buttons that hide the screws. flip the buttons off and the rest is easy. You may find those buttons hold most of the pieces you need to get off in order to attack the wall covering.
