I traveled on Viking Isabella from Turku via Stockholm to Mariehamn.There were many passengers waiting to board,but everything went smoothly.Nice personnel at check in.We had to wait after boarding as the cabins were being cleaned but that's understandable as the ferry only stays in harbour for one hour and there's A LOT to clean. I had booked an inside cabin and my cabin was clean and quiet.No complaints there.
I ate the a la carte breakfast the next morning and I liked it.Much more relaxing than the "regular" buffet breakfast.Great service,delicious food and a relaxing athmosphere.The food on Viking Line is better than on Silja Line.
I travelled from Mariehamn to Helsinki on Viking Gabriella.I had booked an inside cabin under the cardeck.The cabin was clean but there was a bad smell in the corridor outside my cabin.I had expected more noise from the engines,but it was no problem.The only noise I heard was the ding from the elevator that was located right next to my cabin.
To summarize I think Viking Line offers a good product:easy and quick booking online,friendly staff and good food.
