TL;DR We were locked out at 2am and had to check into a hotel.
My friends and I booked this place for 3 nights. We were told that it was self check-in and the door had a passcode (that was given to us 24h before our trip). I confirmed that our arrival would be late at night. Our flight ended up being delayed, but we didn't think it'd be a big deal since we had mentioned we were arriving late at night anyways and it was a self check-in.
So when we arrived at the airbnb it was around 1am and we tried the code given to us and it didn't work. We thought it was us originally so tried it a bunch of different ways and when it still didn't work we tried to contact the host.
I believe the host uses a management company and they said they'd be available 24/7 during our stay should anything happen. That wasn't true since we tried contacting them over a period of 2 hours to try and figure out how to get into the property and no one responded. By this time it wasn't working and we had to contact airbnb to figure out next steps.
Thank goodness for aircover. Airbnb was able to help us cancel the airbnb and get a refund, but we ended up still having to check into a hotel (it was 4am at this point after going through all the process).
Overall, the check-in experience was frustrating and terrible. This hiccup could have easily been avoided, but clearly no one really checks the door between stays.
The management company did reach out afterwards and offer us to re-book the airbnb after our hotel stay for whatever remaining days we were in Austin to make things right. However, one thing of note is that after all of their cleaning fees and nightly cost, it was more expensive to stay at the airbnb instead of a hotel. We mentioned it was their original fault that we were locked out at 2am and had to go to a hotel, so why should we be charged even more for that, before they lowered the price just enough for it to be less than a hotel stay.
