Have taken several European river cruises but had never been to Portugal or on Uniworld. Trip started on land in Lisbon. The Corinthia Hotel was excellent. Our U host recommended a walk to tour the Gulbenkian Museum for our spare time. Outstanding art collection including masters Rembrandt, Renoir, Monet, etc. Next day we opted for an optional tour to the National Palace, Sintra and another palace and the seaside town of Cascais. Worth taking.
Then the journey to Porto to meet our ship. Stopped to have a nice Portugal family country style lunch at a restaurant frequented by 3 other tours. No criticism; loved the lunch. Then onto the old University of Coimbra, its St Michaels chapel and the fascinating old library.
Like all ships on the Douro river the Queen Isabel is by necessity undersized. Our cabin was necessarily very small but somehow the shower was big enough. One criticism of Uniworld's Queen Isabel was that the lounge was dark and they kept shades drawn too much of the day. I missed the open, all windows lounge on Viking. A small ship size issue was only one public bathroom. Made departure day after breakfast coffee problematic as your rooms are unavailable after 8 AM. Suggest they leave the 2 adjacent to lobby cabins open to the public at departure and then clean them last.
Small by necessity. 2nd bag could not fit under the bed because of placement of bed legs. Shower surprisingly big enough.
