Hi Cristina,
Our family have a very good experience in Spain. We always get timely response and help from you. Apartment has everything we need. Room size is comfortable for 4 persons. (1 couple, 2 teenager girls) Safe, clean, bright, lots supermarket stores nearby, 5-10 min to walk to metro station or Sagrada Familia.
No doubt that we'll stay the same apartment if we visit Barcelona next time.
Best regards,
Sam
