First time. Solo traveller and not really done city breaks before (Aside from Dubai). Mainly good food and nice gardens/places to wander round.
Will mainly walk around or maybe the Metro, is it easy to use?
it's a great city to travel solo, first of all if you're flying take the blue bus to the centre from the airport as it's 4€ and easier than the metro (unless you speak Spanish and/or are good at navigating).
The gothic quarter is the most beautiful area to get lost in, you can do a free walking tour as the history is v interesting.
La Barceloneta is the area with the beach - it's not the nicest beach by far but it's still good.
I would def walk around Park Guell as there's nothing else like it.
Restaurants I would go to which are all affordable and mostly traditional are: l'alcoba blava, bodega la palma, bistro sensi.
Bar Oasis for a drink on a nice terrace and my fave hidden place of Barcelona is, placa de sant felip neri - this little square got bombed during the war, has a beautiful fountain and there's a little bar there you can have a drink at! (They use this location for loads of Spanish films).
I think that's enough of my secrets shared haha enjoy!!
