One might think Arwen would harbour some contempt for Men as mortal and overall weaker, as did many of the Elves apparently.
However, Aragorn wasn't just a homeless wanderer (*cough* Beren *cough*). He was the Heir of Isildur, the potential King of both Arnor and Gondor. Moreover, she would have known of their kinship. Aragorn was at many removes her cousin, so he wouldn't have appeared as 'baseborn' and 'lowly' to her as, say, Barliman Butterbur.
In the end though, it was simply 'meant' for the two to fall in love, I think. Like Lúthien and Idril before her, Arwen disregarded the brevity of mortal life and let love guide her.
