Mary's place is large, clean, comfortable and central. The beds are super comfortable and there was nice attention to detail, like a fresh loaf of bread, cheese and milk in the fridge.
We made a work trip and the room configuration was a little odd (1 double with ensuite, then a triple connecting through to a single through to the shared bathroom), so whilst we were okay (we have a close team), some teams might find it doesn't have the privacy they're looking for (e.g. if you're looking for a private room each). For a family, it would be perfect.
Location is great and communication was great. A good place to stay in Hobart for sure.
