MSC Orchestra (together with its sister ships) has 1,275 cabins; 80 percent feature private balconies. Standards balconies are fairly compact -- they come in at 164 square ft. (with 48-square-ft. balconies). Superior balconies are slightly larger at 191 square ft. (48-square-ft. baloncy). Insides and oveanviews are even smaller at 150 square ft.
The cabin was beautifully appointed with red and black color schemes with a double bed (that can be converted to two singles), a sofa, desk, mini-bar, a safe and a flat-screen TV. In addition to regular programming, pay-per-view movies were available; programs unsuitable for kids can be blocked.
The storage space is adequate, but one positive is that the suitcase fits under the bed. The shower-only bathrooms are also adequate and feature soap, shampoo and shower cap.
Some, including my cabin, have connecting doors -- a great family option -- but if you're a light sleeper, avoid these.
There are 18 larger suites though as mentioned; at only 278 square ft. (with 48-square-ft. balconies), they're a bit smaller than suites offered by other cruise lines. Beyond the extra space, the big differences include a separate seating area and bathrooms with a tub.
