If you want a flat to yourself near the happening parts of Austin, I don't think there's a better value pick than Colleen's. The university and city center are only about a 15-20 minute drive in peak morning traffic. As for the flat--first, the AC works great (really important in summer), bed is comfortable, noise insulation is good, has all the amenities you need, and even the decor is charming. Colleen was exceptionally accommodating and communicative with me.
