Well, I'm all about the City of Flowers Penthouse right now, personally. I love it.
Feel free to send me a friend request if you'd like to see it for yourself!
One of my favorite personal space's that I go to a lot is the Bramblenook Farm. Its huge for one thing. You can also raise animals like pigs, chickens, and sheep. You can also grow crops. Plus there's a wood chopping game where you can build furniture with all the wood you chop. It also let's you choose the time of day there as well. It's also in a somewhat fantasy type setting. The graphics in it remind me of the kind you'd see in Fable or Free Realms.
