We stayed at Lubor's place for 3 days while attending a friend's wedding coming from Canada.
Lubor's listing appears to be misleading in the check-in instructions (any time after 15:00). I originally told Lubor that we should be able to get to Prague around 7pm, but that I would keep him posted when we are on our way. We got delayed on our way to Prague due to accidents and jams on the highway, so I called Lubor to give him an update. He got quickly upset about the situation, told me that he was about to leave Prague as he had plans with his wife, and called me his "first troublesome guest." I had to arrange for my sister, who happens to live in Prague but otherwise had nothing to do with the reservation, to pick up the keys for me as Lubor was not willing to accommodate our later arrival.
For checkout, Lubor insisted the keys being handed over in person. We were checking out at 3:30am as we were catching an early flight to Canada. Lubor showed up to the apartment with a blank sheet of paper and wanted to take our passport numbers. When asked for a reason, he said that he wants them for the (quoting his words) "immigration police" and that "he needs to takes down initials of everyone who does not belong to the European community." He insisted on seeing our Czech passports. Once he realized that we are dual citizens, he refused to talk to us in English even thought we asked him to as we feel more comfortable in that language. He told us that in that case, we should "think whether it is a good idea to go to the Czech republic for a vacation." When we left the apartment, he insisted on a thorough walkthrough. Having concluded that everything is in order, he once again asked for an apology for our late arrival. When told that I already apologized and that given how the situation was handled, I was not going to do so again, Lubor told that the he is a landscape architect and that his wife is a lawyer, that he is not a nobody, and that we should stop pretending to be something that we are not. Upon my invitation to speak English again and suggestion that we should record the conversation for filing a complaint with AirBnB, he called us unbelievable and walked away.
Lubor's place is nice (1st star) and Lubor showed up early in the morning to pick up the keys (2nd star). Otherwise, the host';s approach does not reach the AirBnB standards.
Credit to AirBnB: I filed a host complaint with them right away from the airport. They immediately refunded the booking to me and offered assistance with finding alternate accommodation shall it be needed (it was not).
