Hot in the summer. Killer nightlife. It will not take a tourist long to figure out the point of siesta.
Other than that, we like the city, and especially our neighbourhood.
Nobody takes siestas in Spain but the elderly, children and people without A/C in hot zones in summer, and I suppose in some rural towns as well.
In the cities, people do not stop working midday to nap. Now if you are talking about rural towns, that is another thing.
