This is OP. They have some furniture, like a bed and dresser in their bedroom, but nothing like sofas for the living room. My parents moved into this house a couple years ago and have been getting the Slowest Renovation Ever. They brought over their sofa set from their old house, but according to my mom, the workers ruined it somehow, like maybe left it in the backyard and it got rained on? Not sure. Then there was some "misunderstanding" where the head contractor took their whole dining set (they were going to donate it, anyway) and they were too embarrassed to ask for it back. My parents do like furniture (haha, that made me chuckle), but my mom says they haven't been able to take care of one thing that will cause a lot of dust and she doesn't want to buy any furniture until it's done. Which at this rate, I'm keeping fingers crossed it'll happen before Christmas...
I don't want to stay in a hotel and looking at IKEA prices, it'll actually be cheaper for me to buy them an IKEA sofa, a couple easy chairs and rugs than to stay in one. Not sure how to deal with the echo, though, their ceilings are really high.
