I spent one night at a celebrity-loved hotel in Arizona. My $730 room felt like a house.

As I approached Hermosa Inn, I spotted sprawling estates lining Paradise Valley. It was a stark contrast to the small boutique hotel nestled onto six acres among them.

According to the company's website, the Hermosa Inn was built in 1936 as a cowboy's home and art studio. It comprises small adobe structures with turquoise trimmings that look traditionally Southwestern.

The Hermosa Inn had a spa, a restaurant and bar, a fitness center, and 43 guest casitas — each in its own building.

Having a metal key rather than a typical hotel key card made me feel like I was staying in a house — especially since my room was in a private building.

The Hermosa Inn has four tiers of rooms with starting prices ranging from $600 to $800 during the peak season, a representative of the Hermosa Inn told Business Insider.

I booked a deluxe casita for my stay, the third tier. It has a starting price of $730 a night during the peak season, though BI received a media rate for the one-night stay.

The casita's location at the back of the property felt private and secluded. It was situated next to hidden exits, so I immediately saw the appeal for celebrity guests.

My casita was the biggest hotel room I've ever booked. It had a studio layout — just one room and a bathroom.

I felt like I was in an old Western movie with Southwestern rugs and artwork, rustic leather furniture, and wooden marquetry.

The casita had basic amenities like a mini-fridge, a coffee maker, and a safe.

Sitting by the fire was especially relaxing because it ignited with the touch of a button.

The king-sized frame with tall posts looked so traditionally luxurious, and with soft Egyptian linens on top, I certainly didn't want to get up in the morning.

There was also a flat-screen TV near the bed, although I didn't use it.

The bathroom was large enough to fit a spacious shower with two shower heads, a double sink and vanity, and an oversized tub.

Two plush bathrobes hung on the door next to the tub.

I appreciated the mirror's jumbo size more than I thought I would while getting ready in the morning.

The patio out front was larger than your typical hotel room balcony. It had a side table between two lounge chairs and two normal chairs next to a larger table. And even with all that furniture, the space didn't feel cramped.

This final detail made me realize that the Hermosa Inn truly gives visitors a taste of the past from check-in to check-out.
