Fantastic experience: Our real estate agent, John. C. was accommodating and very professional. My daughter took the first apartment she was shown because he listened to what her likes and needs were and shown her an apt. that was a perfect fit. He was easy to deal with and answered my messages promptly. I would highly recommend him.

Negative experience: I had a terrible experience working with John Constantinides and would strongly advise anyone against using them. Communication was non-existent; I would leave multiple messages and emails with no response for days, and even when I did get a response, it was often vague and unhelpful. He seemed more interested in closing a deal than in actually finding me a suitable property, and I felt like he was constantly pushing me towards properties that were clearly outside my budget and needs. On top of this, he was unprofessional and often disrespectful, and I felt like he was more concerned with his own commission than with my satisfaction. I would give him zero stars if I could.

John responded to my request to view the apartment within a few hours and he even went out of his way to call me to be able to best understand our situation.

My wife and I ultimately decided to apply for the apartment, and luckily were accepted, and John was communicative and upfront throughout the whole process. From start to finish, John went out of his way to make a typically stressful process very easy to navigate. My wife and I would definitely endorse John for any real estate needs, one of the best in the business!

Fantastic experience: I've had the privilege of working with John on several real estate transactions. Where he really stood out I must say was with his ability to procure purchasers for properties that were not on the market. These purchasers were also all cash buyers.

John, we've been working together for many years and I look forward to continue working together.

Fantastic experience: John works very quickly and is a no-nonsense kinda guy. We actually almost lost the apartment because there were so many other people interested, but John is an honorable guy, and made good on us being the first to apply. He worked extra hard, going above and beyond to ensure that even though we were renting the place sight-unseen, we had videos, photos, and a personal walk-through over Facetime, where he meticulously measured all the walls, showed us the inside of all the cabinets, walked through the entry-ways, and even showed us a bit of the neighborhood.
