This apartment is located perfectly to discover Barcelona: 5 minutes to the Beach, then along the beach you reach the city center via a beautiful walk in roundabout 30 minutes. And even the great Sagrada familia can be reached in a 30 minutes walk.
The apartment is renovated and very clean and nicely decorated. Sometimes you can hear the neighbors and the school / kindergarten - but I would say it is normal city noise. The street itself is rather quiet. All in all I can recommend the apartment and I really enjoyed my stay!
