Unfortunately not too many people speak english here in Valencia.
If you come for holidays, is easier to find someone who speaks english (because you will be visiting places for tourists mainly, In suppose).
But for living, it could be a bit hard.
Anyway, if you’re planning to come to Valencia and you need help with spanish, or someone to ask anything, I can definitely help you.
It will be good for me too because I need to practice english, so it will be a win - win :)
I hope to see you soon!
