I'll be staying in Barcelona with two Pre-teen girls, and have a room at the top of Ramblas near Plaza Catalunya. I read multiple reports on this forum that the Ramblas is not a safe area. Is this still the case? I chose this location assuming this would be a safe location for us to come back by ourselves from events late night (midnight or earlier). Should I change locations, and if so, to where? Also, how safe is it to take taxis in Barcelona?
