The location of this apartment is unbelievable! It is in the heart of everything and easily walkable to most of the major attractions from Barcelonetta beach to Las Ramblas to Parc Ciutadella/Arc de Triomf. It is down the street from the Picasso Museum and very close to many restaurants and a nice food market. Two metro stops are also quite close to easily get to other attractions like Sagrada Familia, Parc Guell, and the Magic Fountain.
The apartment was extremely kid friendly, from having a pack and play (crib), to a high chair, to an elevator which made getting stroller and other kids stuff upstairs very manageable. There is a nice little playground around the corner from the apartment as well. Having a bathtub and a washing machine also made traveling with kids much more pleasant.
There was plenty of space and having two separate rooms both with queen beds accommodated adults without someone just being in the living room or in a tiny bed.
