I was a little worried about what we were getting into when I initially read the comments. However, what I've realized is that people just don't read descriptions when they book these Airbnbs.
There was no false advertising here. The hosts have clearly laid out all the details you need to know. My recommendation is to take 10-20 minutes and review the locations of the lockbox/airbnb on google maps or something, then read through the instructions once or twice. We had zero issues getting the keys and getting into the airbnb itself.
Everything was exactly what we were expecting and we had a great time staying there. Def. would recommend to someone!
