I had to emergency land (medical issues with someone on the plane) on my way to Madrid, so I wanted to send a friend to pick up the key, which was a big problem for Klevi, so he tried to cancel on me. Making no effort to be cooperative at least a bit, very stressful. When I got there anyways I realized that even somebody in the flat could have just opened the door. He charged me 20€ for that. Door downstairs didn't work properly, but Klevi didn't seem to find it relevant to explain to me how to get inside. Purely stressful and very uncooperative behavior. Flat was simple but ok. Nevertheless, not again.
