We had a very long flight and when we arrived in Munich our bags were lost. It took a number of hours to locate our lost bags. During this time, I had kept our host informed of the delay. Once we arrived at the host's apartment, we sent him another message asking him how we could access the apartment. We waited and waited for a response and did not receive for at least an hour after our sent message. There was no apology, just a rant about not being at our beck and call and that he had four children and couldn't just drop everything to come to let us in. He finally told us where the location of the key was but by that time , we felt incredibly unwelcome. After we left he sent a cordial email thanking us for leaving the apartment in a clean and orderly manner.
