We went to barcelona a month ago on a boozy weekend. We stayed in placa reial, and spent most of our time on las ramblas like most people do.
Personally it put me off the city I really wouldn’t advise carrying anything in a pocket that isnt zipped up! During the day through the hustle and bustle, its constant paranoia!
At night, we seemed to get offered drugs everywhere we walked. We werent exactly shady looking in fact quite well dressed compared to some, but it seems to be a bit of a problem there. You find that the people selling the tat on the street will mutter under there breath, offering charlie or md! Not really what you want to hear whilst admiring the city!
We got surrounded by a pack of ladys who surround you and will follow you down las ramblas, they try to touch you up and invite you back, make sure you tell em to F Off! They take some convincing, but if your just really rude to them (its the only way) they will leave you alone! If not they’ll have your phone and wallet!
A lot of beggars also, tend to come round as your sat outside!
