Me and my 3 friends just stayed at Sam's house few days ago (May 2016). It's the best house we have ever stayed from airbnb. Everything is perfect. We all hope that's our own house :)
The house is beautiful and clean. Cookies, coffee, tea and some simple food are complimentary. Sam is very friendly to be there to welcome us.
For us, the only downside is the heater wasn't strong enough. There's only one heater in the house (living room), it's not sufficient for us to feel warm. (By the way, we are Malaysians that not too used to cold weather).
Overall, we highly recommend this place if you visit Launceston!
