The people are the property is satisfactory could use new gutters so I don’t get soaked entering and leaving my units. Biggest problem I called to pay for my units which I have several - several the automated system wants me to pay one at a time this seems to be a security issue to me , I ask for a real person she says the same things I have ti convince her to pay all at once then I ask to speak to. Supervisor about the antique Online payment system and she connects me a number that just rings and rings then disconnects, another example of corporate doing a poor job of training employees and not caring about customers feed back
