Would we book another cruise with P & O, NO!
These are the reasons: We do not feel the P & O fulfilled their advertised cruise.
Whilst we understand P & O's reasons for cancelling our ports in Argentina, they did not notify passenger until it was too late to cancel not only their booking but also airlines & hotels, even though they must have known months before this was to happen.
Balcony cabin starboard towards the stern, good size, good condition & our cabin steward was excellent. Good shower, plenty of hot water.
The wardrobes opened onto the bathroom door, which was pretty hazardous & the lighting in the wardrobe made it very difficult to see. The bottom area where we had our shoes I nicknamed the "black hole of Calcutta", but this was minor we enjoyed the room.
The balcony while small, had reasonably comfortable chairs, we spent a lot of time on the balcony until driven indoors by neighboring smokers, again P & O, time to curb smoking in cabins & balconies as other cruise lines have, for the sake of your passengers & staff.
