This was a 14 night cruise to Norway, Iceland, (nearly) the Faroe Islands & Orkney Islands. It was our 3rd cruise with Cunard and our 2nd on this ship.
Cabin - Deck 4 sheltered balcony - 4*, Slightly noisy due to some balcony partitions rattling. The Room steward banged in some wedges which did the trick. Otherwise very clean with a great cabin steward. The beds and pillows are vey comfy and we had a good nights sleep every night. The bathroom is small but efficient and the shower was more than acceptable.
Dining - 5*, we were on the late sitting in the Britannia which we prefer. We were assigned on a 6 person table and the other 4 guests were great companyfor the whole period. I don't think we had a bad meal the whole time and most were excellent as was the service. The upstairs Lido is not bad and the food quality is really good considering it's a serve yourself buffet. The whole dining experience is far better than any hotel I have stayed in over the years.
No problems. Very clean and efficient. These balconies are slightly larger than the higher decks so you can stretch out. Deck 4 is the lowest balcony deck and ours was right at the front so a bit of movement but not really a problem. The balcony is metal fronted so in chairs you can only see mountains and sky.
