Awesome spot! My first time staying in Tamarama and I recommend it. It's super relaxed, with the bustle of Bondi is just down the road when you want it.
It is also really easy to get around with public transport only a few minutes walk from the apartment's door. I was surprised how easy I was able to get in to town.
Genevieve is a great host. Her place feels like home, she provides great tips on where to eat, get great coffee, and what to do, and she's so responsive.
