Laura's place is a great place for our big family. There were enough bathrooms for everyone. The location was very close to the Sagrada. There were a few minor problems that she helped us with right away even if it were during very late hours! We would definitely recommend this place for big families.
Only one thing to note is that the building has no elevator, possibly an error in the description. The apartment is technically on the 3rd floor (if you count ground floor as 1st floor).
