Marina was an amazing host. She was extremely responsive. Helped us figure the taxi back to the airport (that was a huge help because we do not speak Spanish; though one can simply take the metro, but we had a lot of luggage, car seats and two little girls). The place had everything you need and was close to the metro. Marina also recommended we discover the Gracia area, which we loved. It is also on walking distance to park Guell. We loved that she had a Nespresso machine.... It helps with jetlag.
Pour one recommendation would be a little bit more labeling and instructions. Using the electric plate was foreign to us.
I would definitively recommend staying there.
