Review of MS Douro Serenity deck 1 (Lower)
- Gymnasium (Fitness Room)
- Cruise cabins from 101 to 115, all of which are Lower Deck Riverview Staterooms with non-opening window. These are "single cabins" and can be booked with no single supplement. Riviera Travel charges 100% supplement for all other staterooms.
- Lift and staircase connect all cabin decks.
