For context we are a couple in our mid forties who have taken many ocean cruises. We took the "France's Finest" trip which is two 1 week itineraries combined. This is a review of Paris and the Heart of Normandy on the Viking Neptune.
When we were on the ship we were mainly pleased because we had nothing to compare it to, but after our second week on the Heimdal we can see that the Neptune has had better days. It is an older ship that has been decently maintained but it simply doesn't have the same features / amentities. That being said, our stateroom was quite large. We had more storage space than we needed. We were happy we hadn't paid for a balcony because the way the ship docked most days (right up against the pier or tethered to another ship) there would have been few opportunities to comfortably use it. The cabin had one North American style outlet but it wouldn't take a grounded or polarized plug. There was one available Euro outlet plus another behind the tv and two more tucked behind the bed if you needed them. The bed was large and comfortable, the window was very large, shower was small and with a flimsy curtain but there was ample hot water and good water pressure. The supplied toiletries had a very strong citrus scent. The provide a hair dryer and face cloths. The room did not have black out curtains. The only real problem with the cabin was the thin walls. We heard the tv next door, we heard people talking next door. The ship operations are also quite loud. Rooms 200 - 215 are right below the lounge so every evening you can hear the activities from above. The newer ships have a better layout to avoid this issue. The noise will last until about 10:30 pm each night.
The staff are very friendly. We appreciated the availability of a concierge to assist with land arrangements. Program director was very engaging and enthusiastic. Twice daily housekeeping was well done. We found the ship was very well organized, everything ran much more smoothly than a standard ocean cruise. Less paperwork, less lining up and waiting, less bureaucracy.
