Compared to most big cities, even in Europe, Zurich is relatively small. Oddly enough, Zurich has 1.3 million inhabitants, same as Milan, the city where I’m based.
Yet, apart from the population, the difference between the two cities couldn’t be bigger.
Zurich old town is mostly pedestrian, making a stroll in the narrow alleys all the most pleasant. There are plenty of cafes and restaurants with al fresco tables where, weather and temperature permitting, people enjoy a bite or a drink without being annoyed by the cars and noise.
