Great place to stay! It is a short walk to La Sagrada Familia. The neighborhood was calm and lovely. There is a metro station nearby that takes you to other areas of the city quickly.
The host was nice and always quick to respond. The apartment was clean and I enjoyed the balcony. Please note that the bathroom is very small. This wasn't much of an issue for me, I just had to get ready in my room.
Overall, a great stay and I would return again.
