This apartment is very good for a small weekend! It’s located not to far away from the city center or the Harbor (15-20min by foot) or 10 min with a cab that will cost you around 10€. You have a good brunch location next door (Federal Cafe) which is comfortable if you don’t wanna look or walk ages for a snack in the morning.
Only negative aspect about the apartment is the poor noise Indikation, you can hear anyone and anything happening in the complex.
All in all it’s a good Airbnb which I’d book again, next time I am in Barcelona.
