I am planning a trip to Barcelona and I am looking for advice on what to see in the city in 3 days. I am looking for suggestions on attractions, activities, and places to eat. I would like to experience the best of what Barcelona has to offer. I am looking for suggestions on must-see attractions, such as the Sagrada Familia, Parc Guell, and La Rambla. I would also like to explore the city’s unique culture and cuisine, so I’m hoping to find some suggestions on places to eat and activities to do. I am open to any suggestions that will help me make the most of my 3 days in Barcelona.
