We just moved out of McMillen Woods recently due to an out-of-state job transfer. I was very impressed with the office staff, Julie was particularly helpful. We never saw a staff person who didn't smile and say hello. They hold lots of events and you can really tell they are trying to create a sense of community there.
The apartments are a great value for the money. You get lots of space (we even had a basement. We also had plenty of parking spaces in our area.
We needed maintenance one time for our AC unit, it just needed charged. They were out the very next day after we called. We even passed by the maintenance guy a few days later and he asked how it was running.
Over all, we were very satisfied with our stay and would recommend it as one of the best apartments in Newark.
