Travelling with friends who are keen "Cunarders" this was my first time on QM2.
I was not disappointed, the stateroom on deck4 was a sheltered balcony which perhaps in the Caribbean or height of the summer may not be ideal however on a winter North Atlantic crossing, which I might add QM2 was designed for, not bobbing around the Caribbean, it was perfect.
The staff onboard from the deck hands to the room stewards through to the staff in Britannia were polite, professional and very good at their jobs, there was always a friendly smile or a hello from all staff when walking around the ship.
Good sized balcony, two table and chairs. Sheltered meaning not open with a glass wall however perfect if you aren't a sun worshiper.Room decent sized and perfectly suitable for two people.
