I travelled many times to Barcelona (and also to other cities around Europe) and I can confirm that Barcelona is best for holidays in any season.
El Gotic, also known as Barri Gotic (’Gothic Quarter’ in Catalan) is the centre of the old city of Barcelona. It is placed from Las Ramblas to Via Laietana, and from the Mediterranean sea seafront to Ronda de Sant Pere.
Ronda de Sant Pere is a thoroughfare in key. La Rambla can be considered a plan of shorter streets, each other than named, hence the plural forms Les Rambles (Las Ramblas). From the Placa de Catalunya toward the seaport, the street is in turn the Rambla de Canaletes, the Rambla dels Estudis, the Rambla de Sant Josep, the Rambla dels Caputxins, and the Rambla de Santa Monica. Construction of the Maremagnum in the primeval 1990s resulted in a continuation of La Rambla on a wooden walkway into the harbor, the Rambla de Mar.
Despite several changes undergone in the 19th and early 20th century, many of the buildings date stamp from Knightly times, about from as farther backwards as the Roman settlement of Barcelona. Remains of the squared Roman Wall can be seen around Tapineria and Sots-Tinent Navarro to the north, Avinguda de la Catedral and Placa Nova to the west and Carrer de la Palla to the south. El Call, the medieval Jewish quarter, is located within this area too.
The Barri Gotic retains a composite street design, with many small streets opening out into squares. Almost of the quarter is unopen to lawful traffic although open to service vehicles and taxis.
Look into other attractions, find out cheap airlines and visit Barcelona. Design your visit because there are so many things to see. And left something to visit next time.
