Saturday night one worker from the apartment's company opened the apartment’s door and would have entered if furniture (previously put by us) wasn’t blocking the door. This act was neither legal nor appropriate as it was 11-12pm. We blocked the door with furniture as there was no key or way to lock the principal door and the previous night (friday night) we heard a strange noise and the next morning (saturday morning) we found one of our phones, which we left charging in the bed’s left side, on the floor near the door on bed’s right side.
Continuing with Saturday night, after the incident we called the apartment's company explaining the situation and one of their workers said he would contact an agent to see if we could be reallocated. We did not receive any answer till Sunday afternoon at 4pm when they sent us a message. At that hour we already left the apartment and found a hotel room as we were not feeling safe in the apartment.
Thanks to Airbnb last night we did not have to sleep in the apartment.
