Kim and Andrew's place is great. We had everything we needed. The beach is just a few minutes away. There are hiking trails along the beach and shore, a small shopping center a 5 minute drive away with everything one might need - grocery, bakery, news agency, post office, etc. There's a bus stop just two minutes away with regular buses into the city - we used a bus regularly to go to central Hobart, see the yachts from the Sydney to Hobart race and enjoy the food and ales at the Taste of Tasmania. There is also a nice restaurant on the shore just a 10 minute walk away.
Kim and Andrew were great hosts with lots of good advice on where to go and what to do - and where to eat on our journeys (thanks Kim!).
While there, besides Hobart, we visited MONA, Port Arthur, Bruny Island, Mount Wellington and the "Women's Factory" from convict days.
