I stayed in Chiaki's backyard house for almost two months, and I enjoyed every minute of it. The house is brand new. The interior is high quality (comfortable bed, rainfall shower, leather couch) and got beautiful natural light during the day. The unit also came with all the basic cooking needs you can think of, which was tremendously helpful for me as I found myself moving to a new city. The A/C and heat worked just fine depending on the fluctuating weather. The house is located in Chiaki's backyard, but access to the house is through a side gate, so you don't have to worry about disturbing the family as you go about your day.
The neighborhood is very pleasant and quaint. I would go on morning runs quite often without issue. All the essentials are under ten minutes away by car. Downtown Austin is an easy 15-20 minute drive (without traffic). And yes on that note, you'll definitely need a car. Also, bring quarters and a laundry bag if you're planning on doing laundry at one of the nearby laundromats.
Chiaki and her husband Nao were absolutely wonderful hosts, along with their two children and chihuahua Morcie. In the unit, they provided recommendations for food and amenities. Outside the unit, they offered other tips and great conversation. I'd absolutely recommend this unit to anyone considering a stay!
