We have a play room/ family room that has a box of his toys in it and we play with him there, mostly just tug/ plush and chew toys that don't cause too much of a ruckus. If the weather is bad for some reason, we'll go upstairs to a really big empty room we have and toss a ball around, but other wise, upstairs is for relaxing. If he's in the kitchen or other rooms, he's expected to lay on the mat or his place and chill (though at 5 months, we're still working on reminding him of that at times). We have inside (plush, chews) and outside toys (balls, frisbee). We control the outside time and outside toys, but leave the inside ones out for him right now since he's teething and having those to chew on save our couch. Once he's through teething, we'll most likely be more strict with picking up his toys.
