Most recommended months to travel:
Any time of year is good, but fall and spring are ideal. The temperature is very pleasant and the prices are lower than the rest of the year.
How many days are necessary:
Barcelona has many attractions that we could spend weeks on, but it depends a lot on your travel style and tastes. However, at least 2 days are necessary to see some of its most touristic sites (including a Guinness at the best Irish pub in the city, The George Payne).
What to pack:
It depends a lot on the time of year in which you visit us. If you come for the winter, at least one thick coat will be necessary. During spring or summer, baggy blouses, short-sleeved shirts, and tops are better.
The best recommendation is that you do not carry a lot of luggage, that you come loaded with illusion and good vibes, Barcelona and The George Payne will take care of the rest!
