Quick summary - We were very happy with this VRBO and highly recommend it if you're a large group that is looking for a nice (and affordable) getaway.
From outside to in...
The location is super convenient. Close to lots of places worth visiting. Blue Mountain, Sauble or Wasaga beach, the Bruce Trail...
Irish Lake is great with cottages all around, but not crowded. It takes about an hour to go around it with the two SUP boards or Kayak provided. There's a dock to sit and watch fish feed from over a glass of wine.
The backyard goes a long way. It's hilly, but worth it. It has a fire pit at the back so bring your marshmallows and live life. Calories don't count on vacation.
The deck is big enough for 8 people to sit comfortably and enjoy the fresh clean air.
The cottage is gorgeous. It's not a cottage in my mind, it's a very nice house. Everything you need is there. Free (and fast) WIFI, a fully stocked kitchen, washer/dryer, huge TV with some movies to watch, a great hard plumbed BBQ, and more.
The kitchen is fantastic with the best drinking water right out of the tap. Full stove, fridge, dishwasher, etc... I'm not kidding, it's not what I expected in a cottage. This is a really nice home away from home. Lots of room for a couple cooks to do their magic.
All of the beds were comfortable and made for some great sleeps.
The owner / operator is very pleasant and responsive.
In summary, we highly recommend this gem and plan on going back.
