Hello from Berlín. Forget the beach, this is the spot :) 1lb of locally raised beef is $4-$5, paid with LN. Views are beyond this world. Air is fresh. In 2 weeks Ive spent maybe $45, but its perfectly possible to live 100% on BTC here. Food, accomodation, gas, bike, ....you are covered.

I estimate overall cost of living to be under $600 a month. Assuming you cook and dont stay in hotels.
