It was relatively easy to do this program!
You pay the fee and Conversaspain does the rest (setting up the job).
They are always there to help and support any problems you have. I recommend this program for the stability and help!
You will need to get your visa, flights, housing, and health insurance. They will help you every step of the way.
You can decide between Madrid and Murcia. I recommend Murcia if you want a more chill place near beaches with good food. If you want the busy city life with other great experiences choose Madrid.
Don't expect your school location to be in the city center of either city. Madrid and Murcia refer to regions so they make up various zones within the region. You might get lucky though although it isn't much of a bother if you don't because public transportation is very convenient.
