I traveled many times to Barcelona (and as well to other cities about Europe) and I can sustain that Barcelona is best for holidays in whatever time of year.

El Gotic, as well known as Barri Gotic (’Gothic Quarter’ in Catalan) is the heart of the former city of Barcelona. It stretches from Las Ramblas to Via Laietana, and from the Mediterranean 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 prolongation of La Rambla on a wooden walk into the seaport, 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. Ruinsof the squared Roman Fence can be seen close to 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 complex street plan, with many little streets opening come out into squares. Most of the quarter is closed to lawful traffic but open to service vehicles and taxis.

Check other landmarks, check inexpensive airlines and travel to Barcelona. Design your visit because there are so many things to see. And left something to visit next time.
