Host forgot about our arrival. After reminding us about 4hrs before official check-in, we were left stuck for about hour and half in front of the apartment doors without knowing door code yet. Urgencies, calls didn't help. As a last resort before asking for a refund, we have called Airbnb helpdesk,who has eventually managed to reach hostand resolve the problem.
Once you get in though, the flat is really clean and beautiful, hence the two stars. But seriously though. I really hhate writing negative reviews, however if you don't want to risk staring at locked doors and feeling somewhat "tolerated" in rented flat, check elsewhere.
