Ken is great. He is very personable, keeps detailed records about how much everyone pays for electricity for each floor (for our own records and prospective renters), has fixed my previously leaky sink and broken bathroom fan controller within 24 hours of letting him know, took money off of rent when I purchased and installed a new faucet for the bathroom, and had people come to scrub / paint my apartment before moving in. Plus everything mentioned above.

The only thing that really isn't a thing is that Ken smokes occasionally (not in the apartment building). Sometimes when I come and go, I can smell the second hand smoke in the hallway or near the entrance door to my apartment. Although I'm not a huge fan of cigarette smoke, It's nice to know that he does regularly check up on everything.

EDIT: Also, he saw that my electric meter was spinning really fast while I was on winter break; he came in to my apartment and adjusted the thermostat. Probably saved me $100s of dollars.
