We were two families with 4 children aged 2 to 6 who lived in the apartment. The apartment has a perfect location, close to restaurants and shopping. As former people remarked, one can be disturbed by the sound from the street. It should be added, however, that only two of the four bedrooms face the street. The rest of the apartment is quiet. The landlord was very helpful with recommendations of child friendly restaurants, arranged transportation to / from the airport. We could leave our luggage in the apartment before / after checkout. The apartment was clean. I recommend this accommodation for a stay in Barcelona.
