My friend and I had a great stay at Sonia's place. The place was exactly as described. It is a small space, but well designed/planned. It has everything that you need for a comfortable stay and an excellent view of Hobart.
It is about a 25 minute walk to town and uphill, however, nothing unmanageable. There is a bus stop very close by and Uber rides to town are only around 5-7AUD.
Sonia provided wonderful hospitality and suggested some great local places to eat. Our favorite was the Pigeon Hole, which serves amazing breakfast and coffee.
I would highly recommend this place for anyone traveling to Hobart.
Tasmania is beautiful and we only wish we could've stayed longer!
