You come to Barcelona for the sun, beaches, the old city and the food, but next time make sure to make time to visit Poblenou - urban district. Some call this area the Brooklyn of Barcelona.
From Born it is only a 15 minutes walk. You need time to discover what is happening in all the old office buildings and manufacturing facilities that are typical for this area, but if you wander the streets you will run into a lot of design offices, small shops, restaurants, co-work places and makerspaces. On May 7th (2016) more than 80 smaller and bigger companies open the doors to show their space and what makes this area interesting.
A good starting place for your 'adventure' is Valkiria Hub Space. Take a coffee, there will be maps of the area and you are good to go.
