Place is fine but note that they make their money on you upon move out. Overcharge to replace carpet - the cheapest carpet available for an outrageous amount. Would've given a better review except for this scam.

We moved in here when it was just being built and called ParkVue home for 3 years. The amenities are great, love the salt water pool, the neighbors are fantastic and friendly, the maintenance team (especially Martin! HI MARTIN!) is amazing and always super helpful and in the leasing office Eli is by far the best. Lots of wonderful memories made here and friends who we still keep in touch with. Definitely check this place out!

The things that are important when renting are the things that ParkVue at Livingston does exceptionally well. The folks in the leasing office, especially Eli are most helpful, maintenance is top notch - particularly this past winter with all the snow. Martin and his team were fabulous. The corporate office always keeps you informed and reminds people to do the right thing. It is kept clean and security system is excellent. I had a great stay there.

Nice, airy, light, apartments but with critical flaws.if you like to eat in. We had a corner apartment in building four. The oven is located at floor level making it all but impossible to use. When we expressed our concern about this with management, we were told we could pay for a different oven. And there are smoke detectors that are so sensitive that just using the oven or even using a fry pan sets off the detectors.

The water also tastes putrid, so you'll want to build bottled water into your budget each month. Many of the kitchen cabinets are set too high to be usable without a ladder.unless you're over 6' 5. This is an animal friendly complex and, at times it felt like living at a veterinary clinic: very noisy. Maintenance is prompt when problems are raised. This is a family oriented complex, with some nice attributes, but for the money, I would not rent there again.

I could give them a 0, I would. Made an appointment and the guy never showed up. I am changing my review from 1 to 4. We called back and scheduled an appointment. The apartments were modern and spacious in a nice neighborhood. It would have been nice if they would have called to say they were running behind.
