We actually live in Austin but wanted to try staying in a few different tiny homes to see if that lifestyle might work for us as a permanent living situation. This was the first on our list that we stayed in.
Communication with the host was great and the tiny was easy to find and enter. There is plenty of parking in the neighborhood. The neighborhood itself is very quiet and has lots of beautiful trees and vegetation. We enjoyed walking around, although there really is nothing within walking distance to do. You will have to rely on the car to do much of anything, but that's fairly typical for U.S. suburbs (unfortunately). If you are visiting Austin and plan to spend most of your time downtown or South of downtown, this location will be pretty far out of your way. You can of course commute down I-35 but there are probably better locations for that. For a more North Austin oriented trip (UT or Mueller or even the Domain), this location isn't so bad.
As for the tiny itself, it was pretty clean and tidy for the most part, although it's definitely showing a bit of wear and tear from use, but nothing major. The main problem we had was that whatever cleaning products were used gave the whole place an overpowering, synthetic fragrance smell that we found very off-putting (think: Febreze). We had to open up some windows and run the fan over the stove for several hours to make it bearable in there. Otherwise, we enjoyed the unit. I'm a pretty big dude (6 feet tall), but I felt quite comfortable everywhere except the shower (had to duck to get under the shower head), and the toilet (not enough space for my right leg while sitting). The stairs and the loft are not super ideal for me for long term use, but they are fine for a shorter duration.
Overall, this is a great spot to stay if you don't mind getting around in the car. It has everything you need for one or two people to be comfortable for even an extended stay. We appreciated getting the opportunity to stay in a tiny and it helped confirm to us that it's a lifestyle we could enjoy ourselves. It also helped us refine the aspects of a tiny that are most important to us.
