Eixample is overflowing with greenery – trees line the quiet streets and you're never far away from a square to relax in. It's home to many beautiful apartment blocks sitting above restaurants and bars filled with locals enjoying summer evenings. Don't forget to look up, as famous modernist architects such as Antoni Gaudí, Lluis Domenech I Montaner, and Josep Puig I Cadafalch have designed buildings here. Walk along Paseo de Gracia to view one of Gaudi's masterpieces Casa Milà and Casa Batlló, and find Casa Amatller by Cadafalch nearby, alongside other gems of Spanish architecture. Paseo de Gracia connects Gracia to the centre of Barcelona. This grand boulevard is home to fashion stores and Michelin-star restaurants. On the subject of eating, make sure you visit the foodie paradise of Mercat de la Concepció. The steel and glass structure was built in 1888 and has been restored to its former glory.
