4124 is a SINGLE cabin, believe me it is SMALL. Recently I had 4182, I cannot recommend it. No counter space around sink in bathroom, had to sit on the toilet and swivel around in order to get my feet in the shower! The shower door was on the wrong side an barred entry from the very small floor space in the toilet.
Dressing floor space was 48 ins by 48 ins. Only one three pin plug in the cabin which was used to run the TV so in order to use hair dryer I had to disconnect the TV. Closet was also small , the safe took up valuable space in such a small closet.
I have been in cabin 4122, its not large but a good layout with door around the
corner from twin beds. Have been on 14 cruises in smaller & larger cabins
and have to say this was a nice small, but not to small cabin.
