I've lived here since September now, and I can actually say that I love it. It's tough to find an apartment and management company that really makes you happy, but Arla did it for me. The apartments are a good size, reasonably priced, and close to a bunch of stores and dining.
I rent a renovated one bedroom. The rooms are all a nice size, although the kitchen is a bit small (see picture), but it works for me. Upon moving in, everything was spotless and ready to go. I can't hear my neighbors at all, which is also nice and somewhat unexpected.
The management company has always been attentive. I had one minor problem which I reported through the resident portal online, and they had made the repair within a day. Also, after a massive recent snowstorm, they immediately began cleanup work, using a plow, front end loader, and snowblowers to make sure the lot and sidewalks were clear and everyone's cars were accessible.
As for complaints, I only have a few. One is the laundry room hours - they close at 9PM, and I get home from work quite late so I often don't have time to do a load of laundry during the week if I need to. I think they should just stay open 24/7 since they are locked and residents have to use a key to access it anyway. There also aren't many machines. The laundry room by my apartment only has four washers and four dryers, so they're often all full. My only other complaint is the one car per apartment parking limit, but I can understand that this is just due to limited space. You get one assigned spot near your apartment, and there are a few visitor spots scattered about. This is especially tough since Nutley doesn't allow overnight street parking, so if you have two or more people with cars in your household you may be out of luck.
Like I said, besides those little complaints I've really loved living here and I can see myself continuing to live here. I definitely recommend checking it out if you're looking to move into the area and there's an apartment up for rent.
