Kristin's Casita is a great place to land in Austin, I stayed for a month when first moving to Austin and definitely recommend! The location can't be beat, blocks from many of the best restaurants in south congress, on a tree lined street that has a nice neighborhood feel. The space itself is super stylish, functional, and the clawfoot tub is amazing. There was plenty of room in the closets and shelves for all of my things, and the bed, sheets, towels, etc we all very comfortable (and I'm a bit picky about those things). The outdoor space is gorgeous and a huge perk, I spent a lot of time working and hanging out under the big oak tree.
Kristin has really thought of everything and is an excellent host, and I can't recommend this Airbnb enough!
