I came to Austin when there were some odd weather fluctuations. This meant that I was alternating between using the air conditioners and the space heaters. The a/c does make a bit of a racket, and not in the good white noise sense. There's some rattling that goes on. That, accompanied with the Austin sirens that seem to intermittently pass by every 30-40 minutes, means that sleep can be a challenge. The bed was not impressive. It's an air mattress that took me a couple of nights to get comfortable with before I was getting good sleep.
During the waking hours, this place is a gem. Traveling solo, it had all the space I needed. I wouldn't hesitate to bring my girlfriend here. I think with more than two people in this space and you're going to be stepping on one another.
The location is a definite bonus as well. Access is easy through the back alley in a slow-paced neighborhood. There are a handful of top-quality eating and drinking places within a 10 minute walk.
