For a ship with magical artificial gravity plates, put in a solarium with comfortable furniture, as above, but set in a blister made of transparent material that allows views "up" and to the sides.

In addition, it should have lots of pretty plants that grow large enough to create semi-secluded nooks. The plants should also smell nice.

For a more "hard science" setting that uses spin-gravity, go with a sunroom, instead. Have a solid deck, below, and bulkhead above, but one wall should be large windows.

Both should have heavy-duty doors that allow them to be sealed off from the rest of the ship, for radiation storms or loss of pressure integrity.

Alternatively, convert one of the hydroponics labs to such an area, only fully sealed and lit artificially.

Regardless of which you pick, include the thick plant-growth and comfortable furniture, and make sure the design has meandering aisles and no straight lines.
