You basically get what you see in the photos. The glowing reviews are true, so I'm going to just skip to the bad parts.
The major con to me is that you might think you're getting a very personal space, but it is very clearly someone else's back yard, which is a bit of a disappointment to me (an introvert) paying a rather large premium for the place. There are much cheaper places offering a much more private experience -- but they probably won't be as lush. It's all about what you want out of your visit!
