Spacing between different text styles

Site URL: https://pike-groundhog-ne24.squarespace.com/merida-centro-new

Hello! If someone can please make a suggestion! I'm sure this is a simple CSS fix and I have searched and tried a few but nothing is working. I simply want to reduce the space between "Plaza Grand" (h3) and the paragraph below (p2) across all pages. This is within an image block (i think!?) Sorry, this is all new to me. Thank you in advance for any suggestions.

Kindly place this into Design->Custom Css

.sqs-block-image .design-layout-card .image-title-wrapper+.image-subtitle-wrapper .image-subtitle {
  margin-top: 3%
}

Thank you so much! It worked perfectly! I appreciate you taking the time to answer!

@JillianMc Just want to say, on mobile, "Accommodations" arrow break in new line.

You can solve by adding this to Design > Custom CSS (to reduce mobile text size)

/* reduce mobile text size */
@media screen and (max-width:767px) {
div.header-menu-nav-item a {
    font-size: 28px;
}
}
