I don't know if you can get a better apartment in Barcelona. The view alone is worth it, a front-seat view of Sagrada Familia.
But also its centrality. You can walk to many places from there but you can also take the metro which is across the street.
The apartment is very clean, and it has all the amenities. The building is also clean, safe and quiet.
The hosts are very gracious and helpful and we had no problems coordinating with them on our arrival.
I highly recommend this apartment, it is worth every penny. 5 out of 5 stars!
Excellent!
