We visited this place on a Sunday evening and the whole street was closed to traffic. Locals were wandering around, kids were playing in the fountains and generally everyone was just having a good time. It was such a pleasure to just stroll down the street and enjoy the delights of the local culture.
We came back the following day and the street was open to traffic - it was still nice, but the place had a different vibe. Not sure if they close the street off every Sunday, or if we were just lucky, but certainly worth a stroll down if you are in the neighbourhood.
