First, the inside of this hotel is gorgeous. The spa is elite. Everything is beautiful.
However the female staff are very uppity, unfriendly, short, and terse.
We also went during a music festival. The average age at the hotel had to be 20. There were people peeing in the bushes. The grounds around the hotel had urine and feces around. All the stairwell smelled. It was like Bourbon Street in New Orleans around the hotel. Stepping away from the hotel just 20 yards was gross.
It isn't near anything charming. It doesn't feel like Barcelona. We stayed two nights and regret it entirely.
This hotel is like a 90s episode of the Real World on MTV.
We talked to other families and other older people staying there and they felt similar.
This hotel is NOT if you are wanting to experience Barcelona. It is nowhere near meaningful Barcelona.
Additionally, on a map, it looks like it is close to the water and beaches. It is. However these locations are all dirty.
Stay in the City Center. Do not stay here.
