Martin did not contact me to tell me the code to obtain the keys. Because it was Sunday and I arrived later than 19 h. ( I already reported that I would arrive at 20 h), but his hour of attention to the public ended. And he did not mind leaving a guest and his 6 relatives including a child on the street despite having made the reservation. I called several times to different numbers and thanks to the cleaning staff I was able to speak with someone who gave me the code to obtain the key. People are first and rules second (the paper of COVID I send to you by email, Mr. Martin...and you leave me in the middle of the strasse). I only wish that you find yourself in a situation similar to mine in another country, having trusted your host. Thanks a lot for nothing.
