Pros:
Check-in was easy, and Colleen was very responsive to requests. There was no toaster in the apartment when I got there, so she quickly dropped one off when I asked for it.
The apartment is about 15 - 20 minutes from downtown depending on traffic, so the location is pretty convenient for SXSW if you can't afford something closer to the heart of the action.
Cons:
The beds need to be upgraded - they have thin foam mattresses which we found uncomfortable.
The blinds didn't block out light very well, so a lot of light leaked in the morning, making it hard to sleep in.
The apartment was not well-supplied. There was no toasted when we got there, and there were no extra garbage bags for our trash.
