I highly recommend Marcela Y Josep's place to anyone who wants to explore a local Barcelona life!
The apartment is situated on the second floor, very close to Sagrada Familia and the subway station (only 5 minutes).
I was surprised by the kindness of the family, the lovely two girls and the cat Michu. It's rare for me to stay with an entire local family, and it's probably the best way to truly embrace the local culture. Although the girls don't speak English well, we
still had a great time.
