When planning dates in Barcelona, be aware of the Mediterranean climate - summers can be hot. Use public transportation or bike-sharing services to explore the city. Try local specialties like paella or tapas. Be mindful of siesta times when planning daytime activities. Check local event calendars for festivals or special exhibitions. Consider purchasing a Barcelona Card for discounts on attractions and public transport. Remember that dinner times in Spain are typically later than in many other countries. Be aware of pickpockets in tourist-heavy areas. Consider the timing of your date, as some attractions may have different hours or special events on weekends. Lastly, while Barcelona is generally safe, always be aware of your surroundings, especially at night in less familiar areas.
