I stayed at the Homestead cottage over Memorial Day weekend. It was my first time there, but my…read morefamily has been going there twice a year for fourteen years. It is a rather quiet locale, with only the occasional loud boaters and barky dogs at whom to make disapproving faces. The cottage we were in had a rather sloped backyard leading to the lake. It wasn't a difficult climb for me, but I could imagine anyone with mobility issues having a more trying time of it, especially considering there are no stairs.
The TVs were plentiful (living room, bar area, bedrooms, even a bathroom), but they don't seem to all get the same channels. They did have a good enough variety of them, though. We even had a Bose radio (the one from the commercials) that put out some decent sound.
Be sure to bring your own bedding (they charge extra if you use theirs... don't ask me why) and paper goods. They had a decent supply of plates, serving dishes, bowls, silverware, steak knives, and (most importantly) a corkscrew.
The lake itself is oddly shaped, but that makes for more interesting boating excursions. Fishing off of the dock right behind the house yielded some bluegill, a perch, a couple of bass, and a few northern. Fishing from a boat resulted in one muskie. The water near the shore isn't too weedy, but it's also not very deep (about 3 feet at the end of the pier).
I have AT&T, and I was able to get 4-5 bars of phone reception and a fine GPS signal, but practically no data signal. The iPhone said it had access to "E" (Edge) data, but about 80% of the time whatever I was trying to do would time out, and that was from the "good" spot near the dining table. There is wifi available at the main area, from what I understand, and also at many nearby shops/coffee places/bars. The ones that do typically advertise with signs.
The closest grocery store is pretty high priced, especially for weekender gear, so try not to forget anything important. Cathy's ice cream is a nice place to go on a warmer day, since it's nearby and has covered outdoor seating. The coffee shop next door to it also has wifi, if you buy something from them first.
