I chose an interior stateroom for this journey as I was not expecting to see great views at the ports we were visiting and the extra cost would not have been worth it. The amount of space I got was reasonable and the furnishings are classic traditional and the bed was very comfortable. The bathroom was small but you soon get used to it and there was always plenty of light and a good water supply to basin and shower. I did however have to call for a plumber twice when the WC vacuum system failed.
The safe provided is a good size but won't take a laptop but my netbook computer fitted snugly. You'll need an EU power plug adaptor and I'd recommend a trailer socket if you have lots of gadgets to charge like me. The shaver point in the bathroom is UK standard size thankfully.
