This alley gets quite busy during the weekend, thanks to a bar just at the bottom end, three floors of music and party, an awesome place to finish off your night. During the day not too much happening, just a bad smell from the garbage of all the restaurants around.
I will go back in the night again, I believe the graffiti deserve more of a dark background, an alley with a mystery surrounding. Is it a dangerous place to be on your own? I do not believe so, although it can be quite intimidating.
