Casa Marina Hotel is as charming as the pictures on the website. The hotel receptionist, Mary, was so kind and friendly. We got to check in early, which was great. The hotel is classic 1920s but with modernized areas throughout. Our room was beautiful! Beachy colors with neutrals and dark wood accents… it was perfect! If you get a room on the second floor you will have the most beautiful view of the ocean through the dunes. The cost per night was less than a larger hotel/resort and gave so much appreciation for architecture and Jacksonville history. And there is a continental breakfast that is free for guests. It was delightful. Everything was amazing! We will definitely be back!
