While I was in the apartment some guy barely capable of english and in possession of a key entered without prior announcement, and without even knocking/using the fucking doorbell. Apparently he was collecting some garbage, but had been neither informed of a guest's presence nor did he seem to care (I did not receive an apology through the host so he didn't seem to think this should be communicated).
Check-in timing was required down to 10 minute precision due to "being super busy" but relying on in-person key handover.
I was asked to give a five star review before even having spent any time alone at the place.
