I actually really like it! Maybe that's just me. And no it's not my house, bloody wish it was. I'm in a crappy 2-bed terrace with a nice 1950s style that we can't afford to do anything about, so this would be a nice step up and I wish someday to be able to afford such a big house.
I'm guessing the description has been left off because they will be dismantling and taking the soft play with them. Personally, I'd have had it going to the first floor so the kids (I) can go up and down that way too, add in another slide or something. I love it!
