The “without owner check in” didn’t work for us. In order to get in the building you have to call a number and automatically the doors will open, something that didn’t happen I don’t know why. I sent a message to owner what to do but I didn’t receive any reply (never). We sat to a restaurant next to the building to wait somebody to get in and thank god 2 girls that were leaving in the same Airbnb, after I explained them what happened, they let us in and help us get in the room. Without these 2 girls maybe we would be still outside the building waiting…
