Ask any homeowner about their experiences decorating guest rooms and they'll tell a horror story of how they tried their best but ended up with something they couldn't even dream of. That's because guest rooms are tricky. Even the best interior designers have to put more time and effort into designing these rooms. Your oak furniture bedroom can be designed according to your taste and personality. For guest rooms, however, you are not allowed such freedom. You have to make sure the bedroom appeals to everyone and provides you with the right look and feel. 
Start with the walls. Make them oyster gray or a darker, darker white. This is a color that you can't go wrong in any room. Avoid white at all costs. It makes the oak furniture room look empty and usually doesn't make a very good impression on the person who has to live in it, even for a day. Dark or warm whites are more attractive to everyone. Moreover, it complements the rest of the theme.
The theme of the oak furniture room will be white and dark grey. Remember, you have to focus on gray furniture and white furniture, and vice versa. The bed will come with a white textured headboard, which will also be replicated on the inner board of the wall unit. The color of the linen should be dark grey. Use a screen behind the bed to give the room a neutral but strong personality. If you don't want to use this screen, you can even choose a painting or a large photo in this place.
Choose a small industrial-style side table, made of metal and painted a dark gray. Add smaller white details here or add white planters or modern light fixtures. The cushions and pillows you use here should also be dark gray. Keep the wall units small, short, and very simple.
You can even add a pet bed to the side of the oak furniture room so guests with pets won't have any problems taking care of them. Besides, pets don't even leave scratches on the sheets.
Use bright amber lights in the room. While gray and white are usually neutral colors, we used a warmer theme. Therefore, to highlight the theme and make the environment warm, you must make sure to use amber lights. Always keep them as bright as possible, as dark amber will ruin the look of this room's oak furniture.
To break up the monotony of the room, you can put a small red pillow on the bed. If you use a vase on the end table, decorate it with bright red flowers to make it look appropriate.
