Really fantastic location, <5 minute walk to Tanunda restaurants and shops, really well situated for any wine tours. Maz was very helpful with suggestions and questions beforehand (especially with us changing our booking a couple of times) and lives very close for any problems.
The place itself is big and everything functions: we even managed to do some cooking on Christmas Day! As with most older houses, a few creaky floors, a bit of dust under the beds etc, but overall clean and nicely presented. There are air conditioning units in the shared areas and front bedroom, and ceiling fans throughout, making it quite easy to cool the second bedroom and keep it cool.
A small note about the area, but a lot of things were closed over the Christmas period. We still had plenty to do and see, but if there are specific places you want to visit in the Barossa, it's worth checking out what their holiday opening hours are.
All in all, we had a lovely stay.
