Victor's places is ideally located for seeing different parts of Barcelona, not just the Sagrada Familia (though that is incredibly close). We walked to Park Guell and Gracia easily from the apartment one day, and to the Rambla and Gothic quarter another. There are travel books in the apartment (which are super helpful if you're totally unprepared like we were) and the apartment had everything we needed for a stay with kids, including a travel crib, high chair, and baby bath. The blackout blinds are in all of the rooms and were very useful for dealing with jet lag with kids. Thanks Victor!
