Had not been to Portugal. Met at airport in LIsbon and comfortable drive to the hotel. Viking again provides a superior hotel product: The Tivoli on Avenida da Liberdade a 5 star stay, spacious and well decorated lobby and restaurant, excellent room and bathroom. Viking worked with the hotel chef and produced 3 different prix fix menus for Viking guests if we did not want to order from the main menu. Tour guides well informed and in good command of English. Because of Covid, Viking's testing procedures understandable and easy to do. The main tour buses (Viking branded) are spacious and comfortable, particularly for the 3+ hour transit from Lisbon to Porto to reach the boat.
The only minus I have is, this being our sixth river trip with Viking, the desserts at lunch and dinner not up to past standards! The selection of included wines at lunch and dinner continue to be good; appreciate that Portuguese wines featured.
