I cherish that. Elevator was very slow but its 60 plus years old. Admire the authenticity of this hotel. Key cards for the room are my ONLY complaint. Should be keys not cards. Staff is absolutely amazing. Right on the beach! Book it. You won’t be disappointed unless you want 5 star 2026\. Thank you for everything broadmore!!!
