I can highly recommend to stay in Daria's apartment! It's a nicely furnished and perfectly clean apartment. You'll find everything you need on here. We also liked the location right next to the Sagrada familia and very close to the Metro Station.
Daria is also a perfect host. Communication with her couldn't be better! It was the first time I booked through Airbnb and Daria is one reason why I will continue doing so! :)
