Was in a pinch when my lease was expiring and they helped me with my options. Very rare in Manhattan to have a management company be understanding and helpful.

This is the worst company I have ever dealt with. The property managers are straight up nasty

Cornerstone Mgt is brilliant. Organized, meticulous, professional and with a sense of humor (much needed in managing any NYC site) that makes it all a pleasure. Cornerstone is heroic with a special laurel to our personal manager the dazzling George Sopasakis.

Ive dealt with several management companies in my time in NYC. Cornerstone is a breath of fresh air. They do what they say they are going to do, and always do it with a good attitude and in an expedient manner. Its just nice to deal with a management company that doesn't make everything harder than it needs to be a sticks to their word. Which is the total opposite of what I have experienced with other management companies. A+

First graders still learning how go to life. One step at a time woops that last step. Corrpt, I wouldn't deal if I was the Grinch. Unlawfully useless organization. Audra the mouth of operation is a good choice for impeached. Who the real estate owner is ta da. You'll never never rent if your interested good luck

Worked with them as a vendor and client for 10+ years. The landlord business is a tough business. You can't please 100% of the population. Things go wrong all the time, 100% of the time, and they deal with it with ethics and common sense. Dealing with them has been a pleasure. They actually pick up the phone (unlike 90% of the NYC property management), pay on time, and treats their tenants and vendors with the level of respect that we all deserve.

This is the most unprofessional company I've ever come across in New York. Stay far far away. So many better options, which is too bad since they've been around a while.
