We really enjoyed our stay at Grasstrees at Anglesea! It's a great space, with lots of room for relaxing. And lots of windows to enjoy the great view. The view from the large south-facing deck is particularly sweet. On a clear night you can see the Milky Way and the Magellanic Clouds. One night there was a spectacular sunset to the west. We didn't even mind the slightly longish walk to the beach (1.5-2 km depending on which part of the beach) because the house's comforts were so worth it. We just had to be cautious crossing the Great Ocean Road as pedestrians, otherwise it was an easy walk.
The kitchen is very well provisioned with dishes and utensils, though the cooking stove was a bit cramped. The gas barbecue was a bit small and somewhat dirty. But we did use it once and it worked fine. As for kitchen condiments there were: a small amount of instant coffee, some tea bags, salt, pepper and a small amount of oil, so bear that in mind when you're packing.
The bedrooms in the main house were comfy and well spaced so that we would not bother each other with our different sleep schedules. The window coverings were great at blocking out light so those of us who wanted to could sleep in. Water pressure for showers was excellent, which can be important when you've got to wash sunscreen off your face and salt water out of your hair!
It was great for our teens to have their own space on the lower level of the house, accessed by separate entrance and with its own key. The one thing that could be added to make the space perfect is a shade or curtain on the window that currently doesn't have one in the downstairs "teen lair." It made it hard for the boys to sleep past dawn, and they are teens, hence incapable of going to sleep before 11 p.m. ;-D The bathroom attached to this separate teen space is really fab, very modern with a walk-in shower. It needs a screen on the window to keep out mosquitoes, but I assume that will be installed eventually (the bathroom is new and was just finished recently).
The week we were there ended up being cool (temps in the low-mid 20sC) so it wasn't great for the beach, but there are so many hikes and interesting things to do in the area that we didn't really mind. We went to Anglesea beach on our last day and the body surfing and boogie boarding were great, as always.
I highly recommend this house!
