The location for the apartment is perfect. It is right next to la sagrada and next to supermarkets as well as the metro.
The place was very clean and we appreciated having a washer/dryer after our travels across Spain.
The only difficulty was not being able to check in early- it would have been nice to have this option. Even when we checked out- the host contacted us to ensure we left exactly at 11am (I understand why they do this but hoped for more flexvibility).
Overall- highly recommend this place.
