Chiaki and Nao are great hosts, and this is a really nice cottage to stay in. I rented it for a month, so I got a good sense of what it's like to be there. One thing that stood out to me is that it's about 3 times bigger than it looks in the pictures. I found it to be very spacious.
The kitchen is nice, there's TV (with Netflix, etc.), good Internet, a good heater and Air Conditioner, a nice bed, and good couch with a coffee table. And the bathroom is nice, too. The cottage is also brand new!
And the location is a relaxed and friendly-seeming neighborhood. It feels completely safe. And it's very comfortable to be there, with plenty of parking right in front of the house, and it's a nice location for getting around Austin.
And, as hosts, Chiaki and Nao are incredibly kind and thoughtful – they went above and beyond in all kinds of ways; and they also gave complete privacy. I could communicate or find them quickly if I had a question, they sent messages from time to time asking if I needed anything, etc. And they're obviously really nice/awesome people. They're really perfect hosts.
I would definitely choose this as my place to stay anytime I'm in Austin!
