Mark's place is very close by the Sydney airport and about a 10 minutes walk from Sydenham train station. It's in a quiet residential neighbourhood with a few cafes and eateries nearby, especially on the way to the train station (recommend the Tinhorn!). Check-in instructions were clear, and the room was impeccably clean. Mark was also especially helpful and brought us extra blankets when we requested for them. A downside was that the traffic was quite noisy at night from the sofa bed - it's softer in the bedroom though if you close the doors.
