We really enjoyed our 5 day stay at Aireys Inlet as we take a break down the Great Ocean Road each summer.
Sally's busy sanctuary was a good base as it wasn't far from the town, however I wouldn't describe it as a beach house as it was a decent and hilly walk to the beach (the closest accessible only by many steps so not great for prams or little kids). Perhaps if we didn't have two little ones in tow this may not have been as big a deal, but we ended up using the car a lot more than we had originally anticipated in order to get around.
The house itself was smaller than the photos make out and fairly basic but well equipped overall. The birds were a major plus, and our little ones absolutely loved feeding them. Downsides were white dog hair all over soft furnishi and rug, which was pretty disappointing given we actively searched for a pet free property as our little ones have pet allergies and asthma; some of the lamps weren't plugged in or near a power point in the smaller bedrooms; lack of toilet paper provided - only 2 rolls left for a family of four for a four night stay; bed linen, particularly on single beds, wasn't great as there were no doona covers on the quilts, just a sheet on top which felt a little unhygienic.
Overall, we had a lovely time as we really love holidaying in the location. But the house definitely had some issues for us in terms of cleanliness and location.
