(this review is for a business stay)
Super-convenient both to the Convention Center and Rainey Street, "Joe's Place" let us house our whole booth crew despite the hotel closures in Austin. The place is about 3/4 of a mile to the Convention Center, about a 15 minute walk except on the day it snowed (yes, really). I might not care to make the walk in the middle of a Texas summer, but any other time of the year it's just as convenient as the Garden Inn, and a lot more economical.
Yes, those three bedrooms are full bedrooms with closing doors, meaning you can house three coworkers, even if one of them snores. If you're staying here on vacation, I'd say you can comfortably house two couples and a friend. There's driveway parking for two cars.
And if you're here for business, you can take advantage of the wifi and turn the dining room into a little hackathon space. Internet access is super-fast, like so much that I was finding excuses to do work at the house instead of the conference.
Otherwise: clean, spacious, good heating and cooling (given that it's South Texas, we had the opportunity to use both), and Joe is easy to work with and fast to reach if there's a problem. If I need to book another business trip near the Convention Center, I'll see if this space is available.
