Stayed at Jutta and Garry's place in June 2021 with my partner, son and mother-in-law.
Their cabin is appointed with everything you need for a short or extended stay away. Importantly for those with young children there is also plenty of plastic plates, bowls, cups and cutlery so you don't need to worry about them breaking any crockery during meal time. Also provided were plenty of toys, books and puzzles that occupied my son when we weren't out exploring the area. The alpacas are also a bonus but watch out for the spitting (though hilarious when it happens to someone else).
Location wise Sorell is a short 5min drive away if you need groceries from either Coles or Woolies, or if you want to order some takeaway (including McDonalds and KFC). The cabin is also conveniently located to allow day trip access to most things in the south east part of Tasmania. During our stay we visited the Port Arthur area to the east twice, Hobart, and traveled as far south as Hastings. All drives were no more than 2 hours.
If we are holidaying in Tasmania again we will definitely be checking whether Jutta's place is available.
