Alright, I just whipped up a paint thing. It should be self explanatory.
For record, the green blips in the main hall are paintings of each crew member, Crow being above the Brown one, which is a grandfather clock. the green circle is a large piece of green marble, as opposed to the standard white that the rest of the hall features. At the front, there is a large oriental silk rug.
Every room is decorated in standard Victorian theme, complete with cherry and oak doors, which are the ---I I--- 's that are placed around. the grey blips are fun fun secret passages.
More on the decor, natural earth tones are dominant, and a great deal of wood trim is on anything that is not already wood. Beds are large, carpets are plush and each room is fitted with it's own differing paintings and plants.
I suggest that something fun is hidden in the library and in the clock.
The secret room should be filled with either blackmail, stolen artwork, weaponry, bodies, or anything else that a proper noble should not have.
Servants are in rooms adjacent to the kitchen, which I Just realized I should have added on.
All of the sleeping quarters are up the stairs, and under there is a secret room to a basement, which could either just be filled with wine and food, common basement things, or more dirt/stolen items/weaponry/bodies.
The paintings might be significant, or just plain set the mood.
Themes that I suggest are famous battles, landscapes, flowers/nature, religious artwork, or simply famous artists. Either way, the specifics of the furnishings should match the theme set by the paintings, possibly differing with each room.
