Rented this house for a week with our entire extended family (my parents, my siblings, their spouses, and all of our kids ages 1-10), and it was a great house for us overall.
First, know that this house is fully stocked with all that you need. Towels, linens, kitchen supplies (spices, condiments, flour, cookware, griddles, pots, pans, mixers, etc. etc). With a large group traveling from afar this really helps as we like to cook and make large meals and many items were in the house already to help us here.
Second, the pics of the outdoor space doesn't do the rental justice. The house is on a point, meaning you have a lot of lake access. There are two piers (both great for fishing, swimming or docking a boat). There's also a patio area down by the water with a metal patio table and chairs. We often sat down in this area for lunch while our kids played in the water and others fished. Swimming was great (not weedy, no lily pads all over), however, if you have little ones, there may or may not be a wading area for them depending on how high the water levels are on the lake that summer. For example, water levels were high when we were here, thus there was no sand to ease you into the water. If the lake levels are lower, then there is sand. Just something to be mindful of.
Beds were all comfortable and accomodating. Note that the upstairs master bedroom is a loft to the area down below. This wasn't a problem for us as the eldest members of our group took this bedroom, and the rest of us congregated either outside or two floors below (as that is where the pool table, dart board and TV are).
Outside deck has one the largest gas grills I've ever used, plus there's a charcoal grill if that is your style. Cooking outdoors on that gas grill was a dream.
Also to note, this is on Long Lake, but NOT the Long Lake that is on the Chain O Lakes. Some people get confused on this. Chain O Lakes is about 20 minutes north, and this is where we went for family fun (like eating out, playing mini-golf, etc).
Our host Doug was quite communicative and really works hard to make sure renters are taken care of. Check-in is also digital, so super easy to check in and check out. Thanks for a great week!
