Nothing makes me more curious in a city than open doors. I love peeking behind them to see what's going on: how people live, where they work and simply discover what's going on behind the pretty façades. When I spotted this classy grey staircase in the city center of Copenhagen, the bright yellow glow called my name. I had a look and took my most liked instagram picture. This yellow courtyard is such a perfect place for breakfast or a break from the city rush. Very invigorating, don't you think?
