My husband and I stayed at Karen and Carol's apartment for 10 weeks when we first moved to Austin.
The location is amazing - right on the Town Lake trail in East Austin and walkable/quick drive to many amazing restaurants/breweries/galleries. Karen and Carol are so sweet and friendly and communicated with us very well leading up to and during our stay. They shared great recommendations in town and it was always a pleasure running into Carol out front in the mornings.
The kitchen was not as well stocked as we expected based on the listing and we ended up purchasing a few items to see us through our extended stay. This probably wouldn't be an issue for a short visit if you are planning on eating out a lot (which would be easy to do given the location). The apartment is mostly open so if you have noisy traveling companions, we'd recommend earplugs. We also got a parking ticket despite using the parking pass we got at checkin, but Karen responded immediately and replaced the parking pass. There's plenty of non-permit parking nearby so we'd recommend parking in those areas if you're worried at all about a ticket.
