Check-in is complicated . Make sure you gonna fill the owners form beforehand. Yeah they ask to fill long form for all guests. Otherwise you gotta wait in front of the door 20-30 min before you do it . In my case we got trade- off : I didn’t fill the form for my family members but sent just passport photos of 5 passports . Anyway had to wait half an hour to get accès code . Fortunately we managed to enter the building hall due to neighbors and avoided staying under rain .
