If you want to take “fun” one-off create workshops, you can find lots of different options on Facebook, Airbnb Experiences, or on 
Viator . Two other common sites are 
Meetup and 
EventBrite . Both of these sites list a ton of activities that are offered online or in-person. In Madrid, great places to take classes are 
Mad's Cool (candle & soap-making) and 
Soho Art Madrid (sip & paint). 
       Spend some time looking at what's out there - you could find the perfect beginner's yoga class, a personal development workshop, or a drawing class. So sign-up, smile, be genuinely interested in people's stories. And if you connect with anyone, suggest hanging out for tapas. There are many 
expats in Spain looking for company, too, as they explore their new home.
