The location is perfect for using as a home base to explore Barcelona. It is close to the metro but in a residential area away from the noise of downtown. In addition, many restaurants and grocery stores helped make this an excellent place for families.
The apartment was perfect; the bedrooms are in the back of the apartment away from street noise (which was minor) and the kitchen, dining room, and living room was ample enough for our family of four. Our only caveat was the mattresses are a bit firm; great for our back sleepers but the side sleepers did complain that they were uncomfortable.
