Had the privilege to visit Gaudi's masterpirece last November. Beautiful architecture and mosaic..Very Whimsical ,reminds one of the chocolate hse from Hensel & Gretel fairtytale. Bought skip the line tickets online which includes a free shuttle bus from town centre .
Pretty crowded even on a weekday, full of tourists , which makes it very very difficult to get a good photo without someone photobombing you in the background. Patience is vital. There are staff members all around who are very helpful and courteous.
We took the free shuttle bus back to the final stop (hardly 10 minute ride away) , from where we had a pleasant walk to Sagrada Familia.
