apartment is in a great location near park Montjuïc, the metro and city centre.
Now fore the downsides: The apartment lacks airco, which means it stays absurdly hot in the nights. Together with the heat the apartment is quite outdated and smells, well terrible. Each day we came back into the apartment at night we noticed the bad smell. Getting into the apartment you can also notice that everything is outdated and basic, but that is to be expected for the price.
Combining al the factors and taking into consideration location, price and the overal state of the place, I can only advise you to rent here if you (and maybe your travel companions) are on a really tight budget.
