I stayed at Bob's for one month and could not recommend this posting enough.
Bob is a wonderful host: generous, attentive and knowledgeable. He has great conversation and will always be able to offer sound advice. He for instance helped organise my roadtrip between Melbourne and Sydney.
The room is exactly as advertised. It is quiet, has lots of natural light and a workspace. I particularly appreciated having control over the room's aircon. The house itself is beautifully decorated, has all the equipment one needs and a quaint backyard (with a BBQ). It proved ideal for my month-long work stay.
Stop looking; you'll be sure to enjoy your time at Bob's!
