A letter from your host
We named it Calyxfor what holds the bloom together.
— Mariel, founder. Superhost · 10 years hosting.
I'm a product designer in New York. I was born in Pakistan. I've spent the last decade learning how to build small homes that hold a moment open. Casa Calyx is the latest, and I think the best.
My partner and I came to Santa Teresa for the surf and stayed for the slowness. We bought the lot because of the wind — a corridor of air that runs from the Pacific to the nature reserve, with our property at the exact pinch where the two breezes meet. When you open every door in the house, the room becomes the jungle. The kitchen smells like salt. The monkeys are louder than the surf, and then the surf is louder than the monkeys, and you start to listen for the half-second of silence between them.
I built the house to do exactly that — hold a moment open. The chef-designed kitchen, the cross-ventilated bedrooms, the office with a desk for two, the pool that's open all twenty-four hours. They're all in service of the same thing: making it easy to stop checking your phone.
❝A house, like a calyx, is for holding something open.
I host with my partner Jano, who lives in Santa Teresa and is the person you'll actually meet if you need something on the ground. He knows every surf instructor in town, every chef who'll cook in the villa, every ATV rental that won't rip you off. He'll set you up.
We've hosted for ten years. We're Superhosts. Our reply time is under an hour. But the thing I'm proudest of isn't the numbers. It's how often guests tell us, on the way out, that they didn't do half the things they planned to. They sat on the deck. They read a book. They slept in. They came back from town with groceries and cooked dinner.
Which is, I think, the version of Santa Teresa worth visiting. And the version of any place worth going back to.
Come slow. Stay a while. We'll leave a key in the lockbox.

In conversation
Five questions, answered.
- 01
Why this house?
We bought the lot for the cross-breeze. The architecture came after. There's a corridor of wind that runs from the Pacific to the nature reserve, and the property sits at the exact pinch. Stand on the deck with the doors open and the house breathes around you.
- 02
Why this town?
Because it earns its reputation slowly. Santa Teresa isn't trying to be discovered. The surf is real, the food is honest, and the locals are kind. We wanted a home in a place that didn't need to perform.
- 03
How involved are you, day-to-day?
Mariel handles all guest communication personally — she replies within an hour on Airbnb. Jano is on the ground in Santa Teresa for anything in person: ATV rentals, restaurant recs, a tile that needs fixing. We're proud of how present we are without being in your way.
- 04
What's the long-stay story?
We added fiber wifi, then Starlink as backup, then a generator that holds through outages. We hand-picked the desk so two people could work from the office at the same time. The 28+ night long-stay rate makes a month feel reasonable.
- 05
What do you wish more guests knew?
Plan less. The first day, do nothing. By day three you'll know which chair is yours. That's the trip.
