I rented a 2 bedroom apartment so that I could have a bedroom, studio, and living room. It is a nice luxery, but I definitely feel you on the whole "feels like a chore sometimes" thing. I get in there and feel like I'm going to work. But that's really just me taking things for granted. It's great to have that space. If more people come over than expected for recording sessions, the excess heads can chill in the living room and watch TV or whatever while we get to work. I used to get so annoyed trying to get a room full of people smoking weed and drinking to shut up because I didn't have an isolation booth/room. I stil don't but everybody doesn't have to chill in the studio anymore so it's all good!
My ultimate goal is to have my living room wired for surround sound (it is, actually, just need a receiver still), and my studio running a line out to my receiver so I can play whatever I want from my studio setup in either room (for guests or just to expand my sound perspective on what i'm mixing). It's really not that far off, I just need some really long RCA cables and a receiver.
When I buy a place I'm definitely gonna hook up some next level "wired for sound" shit in whatever I buy. Run the wires through the ceiling instead of the edge of the carpet, mount the speakers properly, maybe even run the speaker wires through the walls if possible. Add projector to surround sound living room to get the ULTIMATE CONDO MOVIE AND MUSIC ROOM aka burnout-stoner room. can't wait.
