The apartment is in a great location and you can walk (if good on foot) basically anywhere. The apartment has a wonderful terrace overlooking parts of Barcelona and facing the Montjuïc.
The apartment is basically one room with a bed for two, a fluffy, if a bit sat-through couch, a bathroom, Kitchen with a small table. As the apartment is on the fourth floor, its very convenient there is an elevator. I would recommend the place to young couples or friends to stay on a vacation, who are happy to be in each other's presence for most of the time :)
