This was a huge celebration trip. Declared cancer free, 30th wedding anniversary, husband's 65th birthday, husband's retirement. We had a blast. Service, food, tours, amenities all up to our expectations and more. Our suite was wonderful with the balcony and plenty of space. Very clean and our room steward was excellent - as were all the crew!
This is not a cruise for people with limited walking abilities. Portugal is VERY hilly and the footing of cobblestones is tough.
I disagree with one review that says you spend more time on the bus than the boat. You have options. As we headed down the river we decided not to go on the tour and sailed all day on the bow with champagne, cheese, Iberian ham and yummy bread, we'd bought in Spain, and our books. We really got to see the river this way, experience the amazing scenery and going through the locks. We did this for two days and loved the experience. Whole ship to ourselves, pretty much.
