Start your day by visiting the historic center of Andorra la Vella, where you can admire the charming old buildings and narrow streets. Don't miss the Casa de la Vall, a beautiful 16th-century building that used to be the seat of the Andorran parliament. After that, head to the Plaça del Poble, the main square of the city, where you can find many shops, cafes, and restaurants. In the afternoon, visit the Església de Sant Esteve, a Romanesque church that dates back to the 11th century.
