We asked for the entry code before arriving to the property. The host told us it was previously sent and they were resending it to us, even though it was never sent in the first place. First red flag, but not a huge deal. Just no acknowledgement of their mistake.
Second, the host approved us to checkin at 1:00pm on the app. When we got to the apartment they told us that we could not checkin until 3:00pm. We would have picked different accommodations if they had not approved our early checkin request on the app. After communicating this to the host profusely and sending them a screenshot of the 1:00pm checkin approval, they finally let us in, but not before wasting our time. No apology either for wasting our time or for seemingly doing a bait and switch. Very unprofessional.
