I like it, and although it kind of falls into the group of trendy names, i don't think it's a bad name and not as associated with being trendy as other names such as
Avery,
Madison,
Addison etc
I think the name
Alyssa Phoebe is particularly pretty
Any combo's you like? Also i feel it could be a really great nickname for
Alessandra which i also believe is a beautiful name :)
