There are other languages spoken here, including Castellano or Valenciano. It varies depending on which region you live in. There are differences in these languages depending on the Spanish expressions and accents, but overall all three languages are similar. Although there are multiple languages, Spanish is the main language spoken here.
The euro is the main currency here in Spain. One euro is equivalent to 1.11 U.S. dollars, so it is worth slightly more than a dollar. Some stores will take U.S dollars, but most will only take euros!
A bottle of water costs about 1.40 euros.
The best meal I've had this week is paella! It's a traditional Spanish dish made with squid, rice, shrimp (I gave the shrimp away because I am allergic) and chicken! It was amazing, and I wish I had taken a picture for you all, but no worries, I will definitely get this dish again and take a picture for you soon!
