We loved your place. It was clean and perfectly located. You were an amazing host. What we didn't like was how thin the walls of the apartment were. We each had separate rooms and at night (after 11pm) or in the am (before 7:30am) we could here all our neighbors around us talking, laughing, and walking. I think there was also construction in an apartment next to us with constant drilling and banging. We loved Barcelona but with long days walking, we all could have used more restful sleep.
One more thing, upon arrival our host asked us for our Passport pictures with all info. I wish this request was mentioned in airbnb description. I felt obligated to provide my passport but the rest of my family did not.
Overall a good trip.
