Mark and Liz were great hosts! This was my first time travelling by myself for work (I'm a uni student) and Mark and Liz (+ their housemate Ash) were really friendly and accommodating. They are very interesting people who are very considerate and super easy to get on with. I felt very "at home" with them, and I highly recommend people do stay with them! If I'm ever back in Sydney and need somewhere to crash for a few weeks, I'd definitely stay with them again!
