For completeness I will add this last bus section but it took the edge off of what had been a wonderful experience.
What on a clear road should have been a thirty minute journey was closer to 1.5 hours. Bariloche is full at this time of the year as many from the hotter humid north take there summer vacations. The road into Bariloche was choked with cars returning after a days excursion into the mountains. Add to that the bus stopping en route to despatch its passengers at various hotels. Because of the narrow and very hilly streets in Bariloche I was dropped at the nearest junction.
My pre trip fitness regime now came to the fore as I climbed the road for 100 metres before flattening out for another 100. I was relieved to reach the door if my hostel but the pain had only just begun. The hostel was built on an almost vertical hill and there were 70+ steps from street level to my bedroom.
I had a beer then passed out on my bed waking at 6am fully dressed with the lights on.
The benefit in the morning was the view from my bedroom window and hostel terrace.
