We had a great time at Anne’s place in Bronte. Travelled from Scotland with 2 young kids for a friends wedding and it was the perfect spot for exploring Sydney - close enough to Brontë beach and park when we didn’t want to go to far and easy to get into CBD for exploring further afield! Anne was on hand whenever we needed anything but otherwise unintrusive. Loads of kids toys, books etc. which is always a bonus.
The only observation I would make is that both the steps down to the front of the apartment and the steps down to the garden space at the back are both quite steep and a tiny bit uneven in places - we were conscious of our 2 year old going up and down on his own (but obviously no problem for adults and most kids!)
