We came to Austin for a Girls Trip and stayed at Crystal's place. The house was great - had everything we needed and more. Beds were comfy and everything very clean. Crystal was very responsive and left great recommendations.
The neighborhood is what I would equate to Williamsburg, Brooklyn about 10 years - some popular restaurants and bars (especially along 6th st) but also still "up and coming". Being New Yorkers, we wanted to walk everywhere but I wouldn't say the neighborhood is the best for walking, at least not at night. That being said, we used the app Fasten for rides, which was easy and affordable.
Overall I would recommend staying here because the house is so great - just make sure you read about East Austin beforehand so that it matches expectations.
