Pilar's apartment is a great place to a visit to Barcelona! It is very close to La Sagrada Familia (walking distance). There are plenty of grocery stores and restaurants in the area too. It felt very safe and walkable.
The apartment itself is very nice and there is enough space. The furniture is all comfortable (the sofa actually seems upgraded from the photo). The balcony with the view is a cute feature. It is well stocked with the supplies you would need.
Pilar and her husband are great hosts - very responsive and friendly. They were very kind to adjust check-in with us. They also left pizza, cava, coffee, and other supplies for us.
We would definitely recommend this apartment!
