It is a famous street market (thursday and saturday) where you can find everything: from cheap fruit an veggies to quality fruit and veggies (prices are different but also quality), from small "1 euro" products to flowers, from roasted chicken to really good cheese.
The market starts at the beginning of the street (closed to the church) and ends at the end (close to the Square).
Pay attention to prices and follow good smells from the trays to have an original shopping and go back home to eat and cook your choices.
Better to go at the beginning of the morning to find everything, and not crush into people, of course at the end of time market (from 13 to 14) prices are lower, but you have to take what you find!
