This is a good place for a young family. It is good for longer stays in Barcelona because of its distance from more popular areas.
Due to the apartment's boxed room layout, I would not recommend more than 3 or 4 adults. Meaning, 3 single individuals or 1 couple and 2 singles individuals. The location is quaint and bus transportation was nearby and although a little further train transportation was also available to the downtown area.
The only significant concern is the mold issue in the bathrooms, which I assume they will fix. Due to my allergies this created a severe hardship for my stay. Also, the master bedroom is very very small and the bed is composed of two small beds side by side.
Eva and Jack responded promptly to most concerns.
