We embarked the Grandeur in Palma de Mallorca which was without bigger problems, the staff in port was very helpful and it all went really fast.
We booked inside large cabin, which we also had, however since it was oriented "alongside the lobby" it felt quite small. Comparing to the same category cabin on the same class of ship two months ago (Vision), this felt like 1/2. On the other side, 7th floor is great, no noise, close to pool deck (2 floor up), theatre(2 floors down).
The room attandant was not so great, she would reorganise my papers and books on table for no reason while leaving the sink dirty. Only time she spoke to us was the first day when she told us to not use every day a new towel. Maybe she was upset because we did not have prepaid gratuties (we choose to do them in cash) but that is no excuse.
Quiet, nice, however bad orientation which makes the room smaller.
