We are regular Viking river cruisers and had never been to Portugal so this was an ideal way to see the area being sure of great accommodation and food en route !
Our first night in hotel in Lisbon proved a bonus with visits to the area around the city. The ship was typically Viking so, although slightly smaller than Viking's superb longship it was comparable in style and comfort.
As usual the tour guides were superb making the daily included tours very good. The tour to visit Salamanca was particularly interesting as we had a brief foray into Spain.
The Douro river was exceptional with stunning scenery and so narrow in places that you felt you touch each bank with on highlight being the passage through the second deepest lock in Europe.
All in all this was a superb river cruise that we would unconditionally recommend to all and happily typical of the Viking quality and service.
Usuall with Viking we book veranda staterooms but this time we tried a standard outside cabin which was just as comfortable but we missed the balcony
