Upon opening the front door we were greeted with a strong smell of mold. It was coming from the small bedroom where one can see it on at least two of the walls. On the next day we ran the washing machine which broke down switching off the electricity in half of the flat (including kitchen) and it could not be turned on. On the third day, when they came to fix it, it turned out that the oven is broken (Norbert's employees knew that but he claimed he didn't know about it). After that we run the dishwasher and that wasn't working either. Me, my wife and our two kids (5m and 2y5m old) were planning to stay there for ten months. We communicated mostly with Norbert's colleagues Irene and Gabriel who were very concerned. Gabriel showed us a couple of other flats where we could potentially move to, but this was not allowed by Norbert. On Friday morning Norbert promised to fix everything within a week. However we were reluctant to put our kids in the moldy room and don't believe there is a quick fix for this that will convince us to put the kids there. We also didn't want to be there while the renovation of the room was going on. He said they are going to change the whole stove the same day. Around lunch time a guy came to disconnect the gas supply to the hot plates which was needed for the replacement of the stove. But nobody came to replace the stove until Monday. One would expect Norbert to be extra careful after messing up so much with this listing. Hardly anything was working in that kitchen and they disconnected the one working thing there without a reason! Until that moment we were patiently waiting for Norbert to fix the problems but this was the tipping point. We reported the situation to airbnb and they got us out of the long term cancellation policy. We were originally planning to spend 10 months in Norbert's place but luckily managed to find another place and get out after two weeks. In the beginning of the second week Norbert came to the flat. This was the only time we met him although we spoke on the phone multiple times. After his visit he sent me this message: Dear Boris, now that I checked the questioned room myself, I have to to tell you, that you only have to open the window once to make this room useable. The wallpaper is old but their is no moisture and no mold at all. The room is fully functionable and I realy do not understand your complain. We offered you to remove the wallpaper and paint the room, which will take us one day. But if you do not let us in we can't do anything. The new dishwasher will come in the afternoon, pls. let them in to connect it. It will only take a few minutes and...
