Madeleine Auffenberg

"Madeleine was incredible. She was with us through our first apartment purchase on the Upper East Side. She is knowledgeable, professional, and responsive. She helped us with an issue with our mortgage that ultimately saved us a lot of money. Could not recommend her more."

"My partner and I worked with Madeleine Auffenberg to facilitate the sale of our cooperative unit on the Upper West Side, from 2024 to 2025. It was a wonderful experience working with Madeleine – she is always professional, kind, and attentive. Her knowledge and constant support made the entire sale process significantly less stressful. We’ve had such a great experience with Madeleine that we are currently working with her in the search for our next home. We’re thankful that we were connected to her when we first began this process, and we can’t recommend her enough."

"I had the absolute pleasure of working with Madeleine Auffenberg to purchase my cooperative unit on the Upper East Side from 2023 to 2025, and I truly can’t recommend her enough. From our very first interaction, Madeleine was professional, kind, and incredibly attentive. Her deep knowledge of the market and unwavering support made what could have been a stressful process feel enjoyable and fun. What stood out most was how deeply she understood what I was truly looking for—even before I could fully articulate it myself. It was Madeleine who suggested the building and unit I now call home, and it turned out to be my absolute dream apartment. Her insight and intuition were spot on. Madeleine was always available to answer questions, offer guidance, and advocate on my behalf. Her thoughtful approach and genuine care made all the difference, and I’m so thankful to have been connected with her early on in my homebuying journey.I would wholeheartedly refer friends and family to work with Madeleine, and I’d gladly work with her again in the future!"

"I had such a great experience with Madeleine! It was my first time looking for apartments in NYC and she truly made a stressful experience easy and stress-free. She was very responsive, friendly, answered all my questions, and guided me through what can be an overwhelming experience. I would definitely recommend her and Triplemint to my friends!"
-Nicole D.

"My experience with Madeleine was wonderful! I was moving with a very limited time frame. In less than a day, she was able to set up showings for 8 apartments in all the boroughs I was interested in. Since I was moving from out of state, it was extremely helpful to see multiple places in a day, and she definitely spent extra time with us to make sure I was seeing all my options. She was professional and gave informed advice, and kept me totally updated with the application process. I would definitely use Madeleine again in the future and recommend her to a friend!"
-Sydney H.

"Madeleine was friendly, responsive, and dedicated. She provided valuable guidance and support throughout my search. Without her, I wouldn't have been able to navigate some tricky hurdles that popped up unexpectedly. She was an advocate for me, but never pushy, and was always happy to answer questions and/or find answers. She definitely went above and beyond in helping me to find a great new apartment!"
-Anna M.

"Madeleine was absolutely wonderful. She was very responsive to our requests, and was nuanced in her questions. She spent a little extra time with us on our Saturday together and very gracefully kept her energy up (even though I know we were all wilting towards the end!). I'm so happy we were able to work with Madeleine!"
-Alaina A.

"Madeleine was amazing!!! She was super helpful throughout the entire process as my roommate, and I scrambled to find an apartment last minute in the city. She was patient with us, completely honest and transparent, understanding, and just all around fantastic and easy to work with! I would recommend her to any of my friends who are thinking of moving up to New York!"
-Imane A.

"Madeleine was so professional, punctual, honest, cordial, and hard-working. We feel lucky that we got to work with her, and we will contact her again for my daughter’s next purchase and sale of her apartment."
-Veronica O

"Madeleine was so lovely to work with. Was a joy to go through properties with her in the most hectic time of real estate. Listened and knew exactly what I was looking for and found me a great place in a great location. She was a huge support and help throughout the whole process. Would only work with her again!"
-Tyler B.

"I had the pleasure of working with Madeleine Auffenberg in finding my new home in Manhattan. Madeleine made the first-time home buying process as easy as possible, walking me through every step seamlessly. Effective, considerate, and friendly, I'd highly recommend Madeleine to anyone looking for their next home in NYC."
