This was the smallest
We booked an inside cabin hoping for an upgrade but without previous sailings we didn't expect to receive one. We didn't, our cabin was #2015. It is by far the smallest cabin we have ever had on any ship. The bed was configured as a double, but unless you really have to sleep with your significant other, ask to have them separated. Together the room only affords one access aisle to the bed and either you climb across the bed if you are on the wall side or you have the aisle in between the two separate beds allowing both easy access to both. The washroom in the cabin was equally small; you end up sitting side-saddle on the toilet as there is no room for your knees if you tried to sit straight on. The shower is also small, on the faucet side it is at its widest but narrows toward the back. With the curtain pulled across you end up with it stuck to your body, there is no way around that. I just stopped using the curtain as there is a drain just on the other side of the shower lip. Not too much water ended up on the floor if you are careful.
The furniture in our cabin was worn, one drawer front was partially detached but it wasn't one we were using so it didn't pose a problem for us. There is a very small table/stool in the cabin, if you like room service this is what you would have to use. My wife generally likes breakfast in the cabin but didn't use it as it would be too cramped to eat in our cabin. There is a nice flat screen mounted on the wall that cantilevers out, probably the best setup we have seen. The selection of channels is limited but it was nice to have TCM for quiet evenings in after hectic days.
There were two things about our cabin that couldn't be resolved. The first is the strong smell of old tobacco. The second was a loud buzzing sound while in motion. Our cabin steward valiantly tried to use spray deodorizers and an electric de-ionizer to remove the smell to no avail. I knew we would get used to the smell but it was still very present right to the end. If you are very adverse to any tobacco smell do not take this cabin. The humming sound can be quite noticeable at night. My wife and I both wear earplugs when we sleep (so we don't have to hear each other) so the noise wasn't a problem for us, but when I awoke and took the plugs out I really heard it.
