Great spot, great house, near DT, but don't feel you are in DT Austin. Walking distance to many food trucks and great restaurants.
Enough room for 5 people to sleep if you are good with sharing beds.
Sonder doesn't respond via the Airbnb app, you need to download the Sonders app and create a new profile, which is a bit annoying. When you are on the Sonders app, someone responds fairly quickly and get your questions answered.
P.S. - They don't offer early checkin or late check out.
