I was a bit nervous about selecting Garrett's place since it didn't have any reviews, but I'm happy to say that everything worked out well. Garrett was very friendly and responsive leading up to and during my stay. The home was well kept, there were basics available in the kitchen and bathroom that made our stay more convenient, and it was nice and quiet during our stay. The lovely backyard is shared with another smaller guest house, so that's just something to be aware of (which I was, because it's clearly called out in the listing).
I would certainly recommend others visiting the Austin area to stay here!
