Excellent 1BR condo in South Austin (suburban, but very close to downtown) for a couple or single traveler. We used it for a long term stay while deciding whether to stay in Austin long-term while working remotely (we decided to stay!) and looking for an apartment of our own, and it was a great place to be for that. The condo complex feels almost like a camping trip - there's a really cool trail in the shared backyard past the basketball court, plus a pool, and you're close to the Greenbelt for hiking and a lot of great food trucks / open-air restaurants in the area.
The one bit of advice I would have is to remind guests that Austin, like most American cities that are not NYC, much easier to get around if you have a car. This is a condo in the (near) suburbs, so don't expect to be walking or taking public transit everywhere easily. With a car, though, you're <5 minutes from a selection of great grocery stores and restaurants, and ~15 minutes to downtown depending on traffic.
