The space is gorgeous, well-decorated and clean. Super spacious. The location is (on the edge of?) East Austin which understandably isn't as lively/busy as downtown, but has its share of cute cafes and fun spots (not a very walkable area, but that's not a fault of the house, but just the nature of the neighborhood, I guess). It was very easy to get to and from downtown via Lyft/Uber. Sonder also helpfully placed a nice recommendation list of food, drink, nightlife, and shopping on the fridge.
((Sidenote: there's a restaurant/bar/cafe called Sixth and Waller that is about a 7 minute walk away that has amaaazing breakfast tacos. I know Airbnb reviews probably aren't the best place to say that, but if you're staying here, check it out.))
The check-in process to retrieve key fob/door access was almost hilariously elaborate -- we felt like we were on a scavenger hunt -- it involves finding specific entryways, lockboxes, PIN codes, key fobs, more PINs, etc. -- but to me, it means the space is very secure so I didn't mind. However, if you have trouble walking or are in a hurry, it's a little cumbersome. We constantly had to wait until we got outside to request a cab because the walks from the apt to the building entrance took so long.
The host is very responsive on messages, and when we needed a more urgent response (PIN code provided was not working when we were waiting/locked outside the door), they were immediately reachable via phone as well. The checkout process was even easier, as they take care of many of the things other AirBnbs usually require you do (take out trash, strip linens).
Depending on the price of the day, if I'm ever back in Austin, I would stay here again.
