4th recent stay here at present.

First two times, upgraded to a room with a fridge and Nespresso machine. Mini bar with a few soft drinks, mini wine bottles etc.
3rd time, same but only two cans of water in the mini bar.

This time, no upgrade, so a basic fridge free room on floor 6 (although it does have a bath with a shower over it rather than a shower cubicle if someone prefers that).
Desk agent ask if i wanted breakfast as i hadn't booked it, but mentioned it as a diamond amenity and it was added.
Did book it for £81 as some pre-pay promo rate?
