My husband and our two boys (6 and 10) stayed in Mary's yellow cottage for three weeks while visiting Austin. The house was immaculate and cozy. It's centrally located in a great South Austin neighborhood. Mary had kindly written up a nice guide book that points out some good local places to pick up coffee or get a bite to eat which we found helpful.
Mary was easy-going and responsive with excellent communication. When we arrived the house was stocked with breakfast foods, a few snacks, bottles of water and coffee. It was really nice not to have to run right to the grocery store! The keypad system worked really well. One of our boys inadvertently locked us out once as we were leaving and I simply emailed Mary and she had it unlocked lickety-split- before we even returned.
I highly recommend this place for your stay in Austin!
