On one of my recent visits, got to the main gate of the apartment complex, rang the lady and told her I'm outside the gate, she said she'll buzz it open. Grand. Waited 5 minutes, tried pushing the gate multiple times, wouldn't budge. Thankfully a person who lives there came along and opened the gate so I just followed them inside.
Walked around looking for the right building, found it, rang the lady again and told her I got inside the gate and am outside the door. She said she'll buzz the door open. Waited again 5 minutes, nothing. Door still shut. Texted her saying the door will not open. Was about to ring her again when finally the door buzzed and I got in.
I don't mind apartment visits, but the odd time it's a complete pain in the ass
