We really enjoyed staying in Sofia’s apartment. Location is great close enough to walk to downtown Barcelona, just a 5 minute walk to the subway. We loved it is right on top of a Vivari store where we had coffee and ate breakfast every morning. The apartment is very bright with many windows. Street noise was not an issue for us as it comes down at night. It is on the first floor with access via stairs and elevator. One negative is that it only has one air conditioning unit which is in the living room. It was unusually warm in Barcelona when we visited, around 90s, and an AC in the rooms would have been great.
