We had a great time staying with Kathy and Michael during our trip to Hobart. The apt is roomy and has everything that you will need during your stay. It is also very quiet. The only sounds that we heard were the birds in the morning.
The packed cupboard was also much appreciated as we were able to make quick breakfasts before our trips, which saved us both time and money. You will need a car to get around Hobart, but it's only a 20 minute walk to MONA, where you can catch the MONA ROMA ferry into town. We never did this though. You can drive into town just as quick, but if you are unfamiliar with TAS, make sure you have GPS or a reliable international data plan. With the long driveway, it's also helpful to hire a car with a backup camera as well, but we mastered it fairly quick.
It is in a great location if you want to get a mix of Hobart CBD activities along with day trips out of town.
