I traveled on a 7-day Western Mediterranean on the Jade, out of Barcelona. Ports were Monte Carlo, Livorno (Florence), Civitavecchia (Rome), Naples, and Palma de Mallorca.
The Jade was a lovely ship. Admittedly, I did not spend significant time investigating details and running around the ship. To be honest, by the time we were finished with port days, we were way too exhausted to do much of anything!
There were three adult women in an aft BA. It was *tight* with the third bed (sofa bed) made up - but we more than managed. We certainly didn't spend enough time in our cabin to be horribly inconvenienced. The balcony was a wonderful addition, though I probably would not opt for a balcony on such a port-intensive trip again.
Our cabin would have been perfect for two. With three, it was tight - but we knew that going in. The balcony was wonderful - sheltered enough from the noises above, no soot issues. It was cozy and comfortable.
