Hi, Im half Greek half English , 31 and have been in Madrid for a month. I'm working as a teachers assistant but dont speak a word of Spanish so I'm eager to learn. In exchange I can help you with your Engish or even Greek if you would like to give it a go. Available Mondays all day and weekends. I live in Estrella Polar area happy to meet for a coffee in the center.
