Mertxe although English speakers do not need any Spanish (locals and expats are usually happy to speak English), Spanish speakers need to have conversational level English (locals don't like having to speak Spanish in "Englilsh time". Remember, these are not classes, but conversations so when it's time to speak in English, you need to be able to hold a conversation.
nos vemos el jueves, un abrazo.
