Juan Carlos & Nina are amazing hosts and i highly recommend their apartment. All the kitchenware was available, very clean, able to cook and feel as if we are at home.
It only takes 3-5minutes walk to sagrada Familia, there are many local supermarkets (literally a vegetable market just across the apartment), restuarants (including halal restaurants + subway etc), metros and bus stops are all nearby.
As it is based in the city centre, everything in terms of site viewing are all nearby. For example it's a 25minute walking distance to Park Guell. The d50 took us direct to La Rambla and Gothic Quarter.
The apartment is very family friendly, our infant loved it there too and felt really freely and lastly, because the apartment was lovely it had made our holiday much more enjoyable. Thank you so much Juan Carlos & Nina for having us, we already miss Barcelona!
