I came to Austin to do research at the Harry Ransom Center at UT. I could not have made a better choice of Airbnb. Just a few blocks walk to Harry Ransom and the West campus (and famous UT tower). It's a small room with bathroom in a back carriage house. While old, it was very comfortable. Nice bed, good shower, and an air conditioner that kept me cool during six very hot summer days. Also a small refrigerator, coffee maker, microwave, and strong WiFi. Everything I needed! Felicity is a great host. Instant communication. At one point the toilet handle came loose and Felicity had someone there to replace it within the hour.
Only caveat is the immediate area isn't so great. But I was there in summer when it was pretty desolate, so it might feel very different with students about. But a block in any direction takes you to nice streets with lots of food choices, etc.
This was my first solo Airbnb experience and I'm very happy. When I return to Austin I will be booking with Felicity again.
