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.

Barri Gotic, as well known as Barri Gotic (’Gothic Quarter’ in Catalan) is the heart of the former 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 harbor, the street is successively 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 respective changes undergone in the 19th and ahead of time 20th century, many of the buildings date from Medieval times, some 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 knightly Jewish quarter, is located inside this region too.
The Barri Gotic retains a composite street design, with many small streets opening out into squares. Most of the quarter is closed to lawful traffic although open to service vehicles and taxis.

Check other landmarks, check inexpensive airlines and travel to Barcelona. Program your travel to because at that place are so many things to examine. And leftover something to visit future time.
