I am quite sure I have the issue resolved. I pay a few bucks more in rent to live in what I consider a much nicer, secure apartment building. Senor concierge is in the parking area from 7am to 7 pm, plus the daytime cleaning people. 7pm someone comes in to replace him. Small apartment building with only 24 apartments..............The ONLY permanent way to assure no one uses your assigned parking spot, is to have a device installed.......
I just made it clear to concierge that I want no one else parking in my two spots. PERIOD
Once someone was flicking cigarette butts in the parking lot and the managing company send out a memorandum to put a stop to that. I am actually in a building no one plays music loud enough to hear, if they play it at all. I am not living amongst tigueres, just the occasional don't think clear Dominican.
