Hey guys, I have been traveling to Barcelona for quite some time and stayed many times at this Hilton.
I have to say that the quality is no longer of a Hilton. Everything from staff to room quality has dropped. Even the toiletries have been swapped. No room noise cancellation and bath quality were the least I expect to be at par but even that has been disappointing.
Being a member of both hilton and marriot, I strongly recommend the AC Hotel Lilla next door for likely 10-20 euros mores.
Have a great time!
