We recommend staying with Sito! We had a lovely time here.
We felt the location was really nice. 10 min walk to the Segrada Familia, and 2 min walk to the metro to take you downtown. We felt very safe in the surrounding area and it was not too noisy at night.
The interior of the space was quite spacious. Definitely enough room for 4 to stay without getting in each other’s way. The beds and couches were very comfortable. The bathroom and kitchen were decently clean but would benefit from a deep clean.
