Except for suites, cabins are a uniform size and configuration, the only difference between inside and outside cabins being a window/porthole.
The standard cabin is inoffensively finished in blond wood with pastel colored spreads. Two twin beds can be put together into a (scant) queen. There is ample lighting. The desk/vanity stool substitutes for a breakfast table. There is adequate closet and drawer storage for a one week cruise. Other features include a room safe and mini-refrigerator. Cabin television features satellite broadcasts, reruns of ship lectures and commercials for Princess' services.
The compact bathroom (shower only, save for suites) features a small stall that could be awkward for larger passengers. Toiletries are from Princess' spa and include shampoo, conditioner and lotion in cardboard containers.
Suites include large balconies with metal dining tables/chairs and loungers, bathtubs with whirlpools and a sitting area, separated from the bedroom. There is no concierge lounge.
If you are a light sleeper, then you should avoid the cabins on the lowermost passenger decks, i.e. Decks 5 and 6. In certain weather conditions, the waves will slam against the side of the ship and this will echo into the cabins on these decks -- much like a door being slammed somewhere at frequent intervals.
Room with Balcony made it comfortable and flatscreen tv was large (may be too large for the room). 2 chairs and small table on deck. One only chair in room so one person needed to be on the bed. Bathroomis really small and drying oneself a challenge.
