Just returned from Olivia plaza. Cannot recommend enough. Everything about the hotel is spot on... Its Location is amazing...right at the top of la ramblas, the cleanliness is out of this world, the service is outstanding (they even managed to get hold of Barcelona FC match tickets for us), the rooms are beautiful and we got upgraded for free to a suite which included a spa bath. It is well sound proofed and was very peaceful to say its right in the centre! Would absolutely recommend a d we'll be returning soon.
