In a big city like Barcelona is difficult to be in a central place. Anyway this apartment is in a very beautiful residential part of the city, close to park Guell and very close you can find supermarket, bars, coffee shops etc. It was super clean and had a beautiful balcony. The check in with the digital key was a bit confusing at first but then it was easy to use. For 4 guests I guess it's a bit small and the couch does not work perfectly well as a 2 people's bed, but at the end everything went well. Would highly recommend for groups of 3
