This is a nice enough place to sleep if you're visiting Austin and aren't going to be around during the day (the room is a little cramped for just hanging around in, and guests are strictly prohibited). Very simple check-in (that you don't have to meet the host for) is a plus, and there's a powerful AC unit in each room so you don't have to worry about being uncomfortably hot even in the Texas summer.
If you're someone for whom a nice bathroom is a priority it might be worth considering other options, since the toilet basically amounts to a portapotty, and the shower is not the most robust in the world. Is in general clean and functional as a bathroom, though.
The host is very polite and communicative, so if anything does come up it's easy and pleasant to get resolved.
