Great spot especially if you're going to Wellington hospital for a course. It's walking distance to the city and very close to Mt Victoria if you like going for a ramble. There's a bus which takes you pretty much all the way to the weta cave as well!
As for the stay itself- Liz and Sue were fantastic hosts (and their dogs are lovely and super friendly!). They provide toiletries and snacks and have heaps of advice about Wellington. The bed is also very comfy :)
