Hi there. Been to Barcelona for 2 and a half days and thoroughly enjoyed myself there. Must see places
Sagrada Familia- bypass the inside. if you want to take a pic of the whole thing, take from afar, very very far.
Parc Guell-Go inside casa mila very interesting architecture (entrance fee though)
casa batllo (just from the outside is fine)
must do: do tapas bar hopping (gothic quarter theres a lot of bars)
drink hot chocolate and eat churros
shop at lefties and mango outlet (very hard to find though)
buy zara because it's cheap and pretty
see a flamenco show-tablao flamenco is nice, the included buffet dinner is not bad at all. you can book this through a tour website
places to bypass:la bocaria although I've tried having breakfast there, nothing special
picasso museum, did not impress me at all
if you have time, go to montserrat, scenic views and definitely go to Salvador dali museum, very interesting and worth to see.
our hotel was hotel jazz, modern and very nice location
make sure your hotel is in this location, very convenient
transpo- we took subway most of the time- signs in english, very easy to navigate
hope this helps
