Overall, my wife and I enjoyed staying at Maria's place. Location was not walking distance to the main shopping / restaurant blocks (SOCO, East Austin, 6th street), but it was still relatively central. You can walk down to several shopping plazas / food trucks, but not a lot of foot traffic.
You are very close (driving-wise) to the river, in which you can easily find parking and walk towards downtown. I would come back again for the same price.
