Beyond a doubt the worst AirBnB experience I have ever had. The owners had decided not to clean the public spaces of the apartment (trash, bathroom, etc) between guests. I arrived on a Sunday of a holiday weekend. When I briefly let them know the apartment was not clean, they told me to clean it myself because their professional cleaners would not come on Sunday or the holiday Monday. The owners continued to send intrusive, wordy texts that continued for hours and became aggressive and intimidating. By bedtime I was afraid for my safety and had to call AirBnB for assistance. (AirBnB's help line was great).
Besides this, there were other more miner issues. The location shown on the map was not correct. The apartment is above a derelict business and the entry is in a sketchy ally behind the building. The price reflects this. The owners are clearly trying to fix up the place and there are some nice touches including an excellent quality bed.
None of that mattered when I felt unsafe due to hostility from the owners.
