The apartment is in an old building without elevator, there’re ~30steps to get to the apartment in the 2nd floor. The worst thing is; there’re two old school “digital” doors to enter the building but one of them had technical issues to open occasionally even though we entered the right password. The first night, we were stuck outside of that door for 1+hour in the midnight just try the same password again and again, and we couldn’t get the host up to reply our message until 12 hours after. We called Airbnb support but they couldn’t help either. It’s hopeless since our IDs are in the apartment that we cannot get any other hotels nearby. We were lucky that there was person coming out after midnight who helped us to open the door (I rarely see other people in the same building so we feel super luck), otherwise I don’t know where we could stay overnight. The second day, when we were trying to go out, the door was not working in the beginning either (we pressed the button as instructed), we tried 10mins+ to make it open. The unit itself is ok but i won’t risk having no place to stay.
