Small beachfront hotel any island!

Looking for a small boutique style hotel that is hopeful beachfront! Small as in maybe 10-20 rooms. Planning to go in late October for my honeymoon. Hoping to spend around $250-400 a night, not all inclusive but looking for a hotel instead of air bnb. Open to any island or even along the Caribbean side of Central America. Everywhere looks incredible so we are hoping to find the right hotel for us and pick based on that.

We want to hang out and relax and swim in the ocean and ideally walk to some fun lowkey restaurants.

Thanks so much!
