My mom said that our cabins smelled like urine. I couldn't smell it, but she has a sensitive nose, so that's probably why she smelled it. Our stateroom attendant cleaned the walls, and I believe he also shampooed the carpet, but the smell never went away. Also, another negative thing, Royal Caribbean allows you to smoke on your deck and not in your stateroom, so just about every time we opened our balcony door, we could smell cigarette smoke. Those were the only negative things I can think of. Other than those issues, our cabin was wonderful.
