I came here for a week with my family and the amount of space was perfect. I love that there were 2 bathrooms to use amongst the 5 of us.
The apartment location was the best part. La sagrada was a few minutes walk away, the beach was a quick bike ride, cabs were easy to hail, and the train was right downstairs so we could get everywhere we needed.
I did not feel it looked as pretty as it did in pictures nor were we able to access the balcony as the photos made it seem but overall we used the space for what we needed.
I would suggest renting this space out.
