I currently live at Sibley Park apartments and I just googled it to see the reviews. I have lived here for two years now and have had no major problems.
In the last few months there have been some major improvements. We have gotten some new office and maitanance staff that are working hard to create a helpful and welcome environment. The girls in the office very friendly and welcome me by name every time they see me.
I have never had anyone enter my apartment for a random inspection. I have had management come into my apartment once in the last two years, and they had given me 3 days notice. So I am unsure what the other reviews are talking about.
All and all, I am very pleased with my apartment and experience.
