We stayed for three nights, and we used Zen Bungalow as a base to explore Phillip Island. Zen Bungalow is well located, particularly for the GP Moto circuit and the Penguin Parade.
There is a beach in walking distance from the Bungalow (YCW Beach), and other beaches are not too far away.
The Bungalow itself is a well-equipped and cozy place to stay. The bed in the main bedroom is very comfortable, the front deck is a very pleasant place to while away some time, and the was shower nice and hot.
Would be happy to stay again.
