Thank you so much for this incredible review! I am truly grateful for your kind words and for your continued trust over the course of our two transactions.
I always strive to be pragmatic, efficient, and results-based for my clients, so hearing that reflected in your experience means the world to me. I'm so glad we were able to achieve satisfactory results together.
I also truly appreciate you mentioning that I am communicative, personable, and motivated—it was a pleasure working with you! And thank you for the lovely compliment about having a "young at heart motion"—I certainly bring that energy to my work!
Thank you again for your recommendation. I look forward to assisting you with any future real estate needs!
I would highly recommend Costanza Genoese Zerbi & Associates. They worked with my me with the sale of a property belonging to a dear friend, and our experience could not have been better.
From beginning to end, they were patient, professional, responsive, and incredibly helpful. They understood that our circumstances required a little extra care and attention and provided both with kindness and exceptional customer service.
What could easily have been a complicated and laborious process was made virtually painless. Their knowledge, guidance, and willingness to help every step of the way gave our family tremendous peace of mind.
We are truly grateful for the outstanding service and care provided and would highly recommend Costanza Genoese Zerbi & Associates to anyone looking for a real estate professional who goes above and beyond.

Thank you so much, Ruth (and Gwendolyn)! We are deeply grateful for your kind words and trust. Every client's situation is unique, and making sure your friend and family felt supported, cared for, and confident throughout the entire sale was our top priority. It was an absolute pleasure working with you, and we truly appreciate the high recommendation!
Costanza's an excellent realtor who brought a ton of knowledge and experience to the transaction! I had a hard time selling a Long Beach condo for a couple of years, even after renovating it. Costanza was super patient in a slow market, but she made it happen and all while I was out of the country! Could not give a higher recommendation.
Ease of reaching staff: Very easy

Hi Khaled, thank you so much for the wonderful review! Selling a home after a long journey—especially while managing things from abroad—takes trust and team effort, so I’m thrilled we got your Long Beach condo across the finish line. It was an absolute pleasure working with you, and I truly appreciate your recommendation!
Costanza treated us like we are her most important clients. Very communicative, proactive, and provided a lot of guidance and advice that helped us get the right home, not just the first home we saw and without compromising what was important to us.
I couldn't recommend her enough!

Amazing, thanks Alberto. It was a winding course to home identification for sure and I am so glad we took the time to find the right one. Now the adventure begins!
Costanza is a fantastic realtor. She is always available to consult on a property or issue with real estate. I loved working with her and would recommend her for your real estate needs.

What an adventure. Anna, it was such a pleasure to work with you. I am excited to hear about your next adventure!
An absolutely amazing experience with Costanza as my agent selling my property. She is not only experienced and knowledgeable; she is also kind, thoughtful, tenacious, and very responsive. She is thorough and extremely committed to supporting you in having the very best experience. We ran into some funny roadblocks and hurdled them together; she communicated beautifully until the very end when we finally closed. Thank you, Costanza!
I highly recommend her services.

Thank you Monica. This was one of the toughest ones I have had to detangle but it was well worth it. I loved getting to you you in the process and now we both have some great stories from our home sale adventure!
I’ve worked with Costanza twice now and what can I say besides I’ll always work with her. She makes a complicated process easy! If you need someone who is a professional and friendly, Costanza is your go to agent!

We highly recommend working with Costanza. She was highly professional and knowledgable and her expertise was crucial to selling our house in a difficult market.

Thank you Mark! You and Alison prepared the home beautifully. It was an easy sale!
I had a great experience working with Costanza. My situation was very complex given that I was an out of state seller. She handled everything I needed and went above and beyond what most realtors would be required to do.
