We could not check in due to the front door lock being broken when we arrived.
To the host's credit, they were extremely responsive when I messaged informing them of the broken front door lock. They immediately called multiple locksmiths in the area to find someone who could fix it ASAP. The soonest the locksmith could arrive was several hours later, so we decided to just take our luggage with us and go explore around town to try and salvage some of the afternoon.
The locksmith arrived and confirmed the lock could not be repaired on-site that day, thus we had to book a nearby hotel.
In my mind this is an automatic 1-star experience, but I added a star because I do thank the hosts for their responsive, friendly, and respectful communication throughout the ordeal.
After the host processed a refund, we still had to contact Airbnb support to get tax + service fees refunded which was a terrible experience. We'll be staying at hotels much more often from now on.
