This bus is such a lovely retreat! It rained the first day I was there and I just hung out in the bus for much of the day listening to the rain on the roof, which was a delight. No shortage of necessities and some cool spots in walking distance, with much anything else you'd want to do an easy bus trip or bike ride away. I'll definitely look to stay here again when I visit Austin!
One caution for light sleepers: The same thin metal walls that made the rain so lovely also meant the traffic noise from the nearby busy road was noticeable. You might want to bring earplugs if that's something you expect would bother you.
