Stay Safe: When it came to taking taxis around Barcelona, I brought a mifold Grab-and-Go booster seat, a super light-weight foldable booster that’s small enough to fit in your purse. When walking around, we quickly learned that the traffic signs in Barcelona mean business. A flashing green man or hint of yellow was NOT the time to attempt to cross the street. The traffic lights change quickly, the cars waiting at the stop lights are unforgiving so it’s best to wait for the next light instead of taking your life in your hands. Don’t count on pedestrians having the right of way.
