I'll get you started.

It's impossible to tell from the photo what the colors in there are so I won't be specific.

I think the chairs are a little office like. Purchasing new ones in a color you like is the obvious choice. Or you can reupholster either the whole chair or just the seat. If you could do just the seat easily, pull the chair color and find a patterned/striped fabric with that color. Your mirror looks to be hung about six inches too high. Curtains using the the same fabric as the chairs, or one of the colors, would dress the window. Fresh flowers or a good sized real orchid on the table would be simple and pretty.

Last, for this table four chairs would look better for daily use. Do you need six, or can you store the other two for when needed?
