Very clean and very basic - but *don't* let the basic part fool you. For as basic as it is, it was a wonderful place to stay. The bed was comfortable, there are two tv's, the kitchen has a nice selection of cookware, and there's a nice table/chairs on the patio. The neighborhood is quiet and we had no issues. Depending on traffic, it's a less than 10 minute drive to downtown; not a long trip from the airport or the Eastside bus station. The host checked in daily and was very clear with check-in instructions and how to use the electronic lock.
(A side note about the bathroom: very well lit, decent sized, but the shower is a smaller shower and the head is affixed to the wall. There is a step up into it and a step up into the bathroom as well.)
It's a lovely unit and would absolutely stay here again if I find myself on an visit Austin weekend.
