### Featured Review

**★★★★★ — Joel Posner, April 2026**

> Walking into my newly renovated home in Hewlett wasn't just about seeing a finished project; it was that quintessential 'reveal' moment where vision finally meets reality.
>
> For eighteen months, I lived away from my residence during this major renovation. It’s a daunting process, but Interior Serenity acted as the ultimate stewards of my vision. Much like the approach Drew and Jonathan Scott take—balancing structural integrity with personal style—Simi and company didn't just move walls; they understood exactly how I wanted to live.
>
> They took my specific needs—from complex technical integrations to the fine-tuned details of the living spaces—and executed them with rare precision. The final product is truly timeless; I feel a deep sense of gratification working with professionals who respect the 'bones' of a house while modernizing it for the future.
>
> I am finally back home, and the sense of peace I feel is a direct result of their commitment. If you want a team with the expertise of a master builder and the heart of a storyteller, look no further. They didn't just renovate a house; they gave me my home back. I am incredibly grateful.

**★★★★★ — Goldy Gluzman, April 2026**

> After years of searching, Simi found us exactly the kitchen faucet we'd been looking for.
>
> We had a very specific vision — something distinctive, not the same style you see in every showroom. Simi listened carefully, understood what we were after, and came back with a small, perfectly curated set of options. No overwhelming choices, no pressure to decide before we were ready.
>
> Her patience and professionalism throughout the process made all the difference. We're thrilled with our final choice — it's exactly the piece we'd been hunting for years. Highly recommend!

**★★★★★ — HU-82398310585, March 2026**

**★★★★★ — Josh Justic, May 2023**

> Simi took a generic commercial apartment remodeling project, and produced a living space that was visually stunning and very attractive to all potential rental clients.   The bathrooms designs were exceptional, the kitchen was amazingly attractive and inviting.  All in all, I am very happy to recommend Interior Serenity for your next project.

## Community Q&A

**Q: where is the lighting over the bath from?** *(in Photo Questions)*

Looking at the lighting

A: Hello Lauren,
Thanks for reaching out. We use many lighting sources, and I can't remember off the top of my head who we used for this specific project. We may have used Elements in Carl Place, Long Island (they have great selections),  but don't quote me 100%. 

Feel free to contact us should you need design direction or consultation. We offer a complimentary meet-and-greet to discuss your overall project.

I can be reached directly at 646-770-7090.

Thank you & Have an awesome day!

~ Simi
