Swansea was just an overnight stop to break up our drive from the Bay of Fires to Hobart, so we (me, my wife and kids and my wife's parents) weren't expecting luxury. Or really much beyond a comfortable bed. However, this place looked much better than the photos (because the photos are terrible). The beds and towels were clean and so was the house. I'm pretty picky about cleanliness, and I didn't see anything to complain about. Also, the driveway was able to accommodate a passenger van, but I wouldn't try to fit a camper down it.
An odd feature of the house is that one bedroom and bathroom are essentially a separate apartment that you have access to, and you enter that apartment through the bathroom. It's awkward, but unless you have four groups of people that each need their own room, the main apartment is sufficient. We only used the second apartment when the main apartment's bathroom was in use.
