Extra changing table..

So my babys nursery will be upstairs where all of our rooms are. I'm trying to think of a way that we wont have to wall all the way up stair every diaper change and a way to keep my living room from being cluttered with diapers and wipes! Lol we have a side office that's like a room size, do you think it would be tacky to have a changing table in there?? Other wise we have a room that is supposed to be used as a dining room that isnt used for anything really, it could go there to? Any opinions or suggestions??
