The apartment is super nice, specially the balcony (there isn’t a cover anymore but still nice) with a beautiful Barcelona view.
There is air conditioner in only one bedroom and the leaving room.
It is well located, close to the subway, walk distance to many tourist spots and a grocery store next door (and many restaurants and bars).
The only downside was the smell of cigarettes. We kept all the windows open every single day, and even after 5 days we could still smell it in the apartments.
