Everything is as described. Showers have hot water and the couch functions as a 2nd bed.
It's best to have a rental car as the heat and distance make biking slightly inconvenient and parking is easy on the east side.
Lastly, fear not the air conditioning works just fine. Put it on the third (high) setting and it cools to low mid seventies which feels super refreshing in Austin heat.
Would stay again.
