1. Public transport is good, get a Metro card with ten tickets, it can even be shared simultaneously.
2. Beware of pickpockets.
3. Credit card acceptance is high, but not 100%.
4. Paella, a rice dish, is famous in Barcelona

Day 1

Start your day with a walking tour. I would recommend Sandeman’s walking tours. In the afternoon, check out the History Museum. It is pretty detailed and has remains of the historic Roman city of Baracine.

Day 2

Then head to check out Gaudi’s architecture at Sagrada Church (which is under construction for 100+ years), Casa Batllo, Casa Mila, or Palau Guell. All of these have hefty entry ticket prices, and I would recommend going inside at least one of these.

Head towards the beach, Playa de Catalunya afterward. There are several road-side vendors, some selling food and some cheap knock-offs of popular brands.
