The internet didn't work well, but that's the least of my concern here. While I was asleep, a woman entered my "locked" apartment, without knocking. I was literally terrified as I was awakened from my sleep with this woman standing in my door; there isn't a proper inside lock at this flat.
...When I immediately reached out to the host, she said 'this was probably her cleaner going into the wrong apartment by mistake'.
Nightmare! I literally screamed and the woman in my flat seemed unphased. She knew what she was doing...
