Small,but how much time do you really spend there.  Read entire member review.

Cabin 137 was on the port side and usually faced out to the river - a plus. There was no electronic card for the door, but a rather cumbersome key. The beds are comfortable, but when moved apart to make twins, so narrow! There is a big picture window, but they hang a curtain over it that we managed to pull together with a rubber band to see out. Tiny bathroom, but doable. All the cabins on the River Baroness are the same, just location makes the price difference. Plenty of room for clothes. A chair and little table, but you couldn't put the two together. Shelf that I guess might be for a laptop when propped up. Plenty of plugs including a 120. They supply bathrobes, hair dryers, all shampoo, soap, lotion. A very functional room, don't spend time there anyway! Never interfered with sleep from engine noise, although almost the back of the ship on the first level where the dining room is located.  Read entire member review.

All cabins are the same regardless of Category - no balconies, windows don't open. So no need to pay for an upgraded room. Rooms are very small but plenty big enough for 2 people. Room was in the back on the bottom deck and on the 2 nights the ship was moving there was quite a bit of engine noise.  Read entire member review.
