You should stay here! The valley is beautiful and very relaxing, the goats are cute and it's actually quite close to the city by car.
The place itself is small but nice and has a full kitchen. Two things I'd note is that the internet can only be used inside and to get to the third bedroom you have to walk through the second one, so keep that in mine if you like a lot of privacy.
I'll definitely try to stay here again next time I'm in Hobart.
