Guest houses in Miami

"After checking in, I put my luggage in the room and left quickly to take care of some work. When I came back, I found an elderly woman and a Black woman behind her entering a code and unlocking my room door. I immediately went up to question them, but I got no response. They even blocked me outside the door. By the time I managed to get into the room, both of them had already left. I then messaged the owner, but received no reply at all. This situation made me feel extremely unsafe, and I couldn’t sleep the whole night. My laptop, tablet, phone, and bank cards were all inside the room. I do not understand how they knew the code or why they were able to open my door. This experience has seriously raised concerns about the hotel’s security and management."
