Several different friends of a friend have stayed there and loved it. We're staying there for the first time in Spring 2011. We rented through a private owner, and he's been great to work with. The drive to WDW is supposed to be very short, the pools are supposed to be very nice, and it's centrally located. We will not be going to the parks most days (heresy, I know...but staying onsite three nights before going to the condo) so having a comfortable place to stay was important to us.
As with all private owners, there are risks (ie we've already made a deposit, and will have to prepay the rest as it gets closer). We checked reviews, trusted our gut, and went with it. (We've done condo rentals elsewhere before, and always had a good experience.)
I'm a little surprised how infrequently it's mentioned on these boards, although I have heard that rentals have been discouraged to some extent by...the homeowner's association? (Someone/something.)
