We weren’t able to check-in, the key lockbox was empty. We had to try a second lockbox, probably for another apartment (we don’t know)? But the second lockbox was empty too. In that situation, quite late checkin, already dark, around the parking lot where the lockboxes are, where a lot of dubious people so we weren’t feeling safe anymore and asked for a cancellation. With the help of airbnb support it was possible. Communication could have been easier and faster in that situation but it worked out in the end. Comparing the other reviews, we may had bad luck.
