I like it, as a southern European name. It's "clean", simple, and handsome. But it's become very popular even in Scandinavia now, and I just personally think it really sticks out awkwardly when Norwegians name their kid "Mateo". It's like a Spanish family naming their son "Thorbjorn" or daughter "Sigrid". Not that you can't use names from other cultures, but consider how it sounds in your local name culture.
I'm really surprised by these comments. I think Mateo is a nice name with an irresistible Spanish charm. It is strong, handsome, and it ages well. I think “Matt” and “Teo” would be cute nicknames. Overall, I think Mateo is a lovely name.
I love this name! I named one of my characters this. Outside of my own character, the name reminds me of summer? It's a warm name, at least to me. I think it's a solid choice, and it has some cute nicknames.
Sounds strange. Little bit dry. I don't know what to say about this name, but I just don't like it, even if it's not bad, still, something feels missing.
