is it double duty room? need for it to function as an office too? or do you want to convert it to guest room only? what has to stay in a room? what has to go? something you're especially attached to?

remodel and decorating are two different things..I take it you want to restyle it rather than remodel? am I correct?

the room has a good potential...love the floors

determine the function you need to get out of it, and tell us a bit more about your preferences (style? color? anything we can know in order to be more helpful?)

I imagine you'd need more lights..window treatments(even though I don't know whether you need them for privacy etc. But they'd make the space softer). Is the rug staying? if yes should go where serves a function, say next to a bed.

But first tell us what do you expect out of this room in general
