Staying at Martin's and Ondang's place was my first time using airbnb, and traveling to Sydney. The two hosts were very welcoming and went out of their way to make me feel comfortable in their place. Martin was able to spend some time to show me around Sydney and tell me a bit about the city. He was also very accommodating, as one of my friends needed a place to crash at the last minute, and Martin was ok with this.
Overall I enjoyed my time in Sydney and was grateful for the fact that Martin was able and willing to show me around Sydney, and take me to the airport on my last day there. If anyone else is coming to Sydney for the first time, and would like to stay in a place close to the city with people who are happy to show you around, I'd say this is a great place to start.
