I came in Sept 2016 with my mom, husband and 15 month old daughter. There was a road race at Loch Ness that brought us here. The cabin was spacious and while it is new for us to pay for electricity with a coin system, it wasn't that bad actually. Allan came to check in, and the place was well-organized and the kitchen has everything you need. The beds are pretty comfortable, and it was easy to find the place once we got used to the layout of the property. Note - the water pressure is non existent, (drips) but the temperature was hot. The washer worked fine, but we could not get our clothes dry. Minor things, not a huge deal.
The biggest piece of advice is Drumnadrochit and this lodge is RURAL. There are places to eat and some things to do, but you are sort of in the middle of nowhere. This also means the phone/3G reception is pretty terrible (I had AT&T). And, there is no wireless - so if you need to check online for anything, or check emails, you really can't (unless you use data, if you can even get service).
We would recommned if you need to stay in that area.
