From the research I've done it sounds like a pretty nice option.
They have a shuttle that take people to the TTC - not as often as if you were staying with Disney - but at least from what I gathered it's the only property on the shuttle. It drops only at the TTC - but in the afternoon and even picks up from all 4 parks.
It is still not completely finished - but apparently the main pool and lazy river are complete. There are no "restaurants" at the moment, but the way I look at it in our case we'd have a car, so DTD is not that far, nor other restaurants off property.
The decor looks lovely - granted, not themed, but very pretty none the less.
While technically it is NOT Disney property - it is completely surrounded by Disney property.
I've read comments on other boards that there are two "views" - one is of the lake - the other is a "parking lot view" ... but from some of the units of the larger building you can see the fireworks over Epcot - and someone saw a special fireworks display over MGM as well over the holidays.
We're looking at this as an option if my sis-in-law can get an exchange for us. I like the idea of being so close - yet not having the cost involved in staying "on property"... we'll see.
