The lower deck of Solace, mainly home to the cargo areas in front. As well as the passengers quarters in the back of the ship and the ship's infirmary. The staircase in the passengers corridor leads up to the galley on the upper deck. If you walk out of the door you'll find yourself in the back of the cargo bay, where the skiff is located. The cargo bay is higher then the passengers area, and holds another level of cargo platforms reachable by stairs. There's a stair on each platform reaching up to the upper deck as well. In the front of the cargo bay the cargo bay doors are located, not a shiny idea to open those in space.

The upper deck is mostly home to all the activity during the day. It's home to the crews quarters, the galley at the back, and at the utmost back the engine room. And not to forget the bridge in front.
