We stayed in one of the cubes, which was my first time in a ship container and I loved it! The space was super efficient and cozy, clean, and with sufficient amenities. The space is just a few minutes walking from the port, so it's an excellent location if you arrive to Naoshima from Uno Port. The only sad thing is that we had a food coupon we didn't get to use because the place was closed :( Quite convenient self check-in and just walking distance from a convenience store.
