Most aft Princess cabins are suites but there are a few of what are called outside double with balcony, they are a standard size cabin but have a balcony, not a bad cabin. Just stay off the Emerald deck, the aft cabins tend to be noisy, both from some of the surrounding equipment and the noise of the wake when above 12-15 knots but Baja, Caribe, and Dolphin aren't bad. Next issue is movement, if you are in calmer waters there is no problem, if the seas get a little rough the movement tends to be exaggerated a little and you will get more motion than a cabin towards mid ship, so if anyone is prone to motion sickness probably not the best place to be, again depends on where you are going and the condition of the seas. We have been in aft cabins several times on Grand Class ships on the Mexican Riviera and have always had smooth sailing, then again motion doesn't bother us so if the aft is rocking and rolling it is no big deal to us. It is nice to sit out on the balcony in the early evening with a drink and just watch the water go by.
