We had a short and pleasing stay at the Ditty Studio. It has a great location in North Hobart and is a very short drive from the City Centre with off road parking available for free. We didn't make use of the buses but these are also very regular if needed.
Trish was very friendly and very accommodating, allowing us use of her kitchen and also a late check out which we really appreciated.
It's a great space and perfect for a short stay close to the City.
