Hotel in Lisbon was very comfortable and the Viking staff very helpful and welcoming. City tour interesting.
Excellent service on board the ship. Meals were all excellent. Cabins comfortable and spotlessly clean.
Unfortunately there was too much walking for me and the trip to Salamanca, was enjoyable, but the walking in the city for the tour was too much. Using the tourist train in the city tour would have been better for all the folks with walking difficulties.
