We frequent different lakes in the region every year and loved our stay at Turtle Cove, aptly named, as we saw a few turtle friends during our stay.
Location: the Cove itself is very secluded and safe -- our 5 and 7 year olds could swim across to the other side by themselves without concern that a motorboat or jetski would blow through; yet the Cove is also at a great spot in the lake, itself, so access to get out and explore (we rented a boat) was extremely easy. Only about an hour to the opposite end of the lake where there were little islands to explore. The grocery store isn't particularly close (20 minutes or so) but there are smaller markets with a few convenience items within a few minutes of the house. We visited Rosemont Winery, which was extremely quaint and relaxing, and only a few minutes away from the house.
House: the house and kitchen were well equipped, and the rental property manager was very responsive -- our soap ended up being low but she showed within hours of us calling. The dock is the real sell, here, though. Both the upper and lower decks were expansive, and could fit our family of six all sitting or lounging next to each other VERY comfortably. They also had all the toys -- Kayaks, paddleboat, paddleboards, floaties, chairs, etc. This is by far the best dock we've ever found at a rental, and the shade was a huge plus given we had grandparents who don't swim.
Owners: Leah and Rob were awesome, and very attentive. They were lovely to deal with and made sure we had everything we needed!
