The only problem with my stay was the soundproofing and the air conditioning.
The room faced the Placa de Catalunya and the noise from this area is constant throughout day and night. Daytime you have tourists and traffic and and a Grand Piano for people to play and the night Road Sweepers clearing the area and the window double glazing let the sounds in.
The air conditioning ( we like a cool room) day and night, but the setting can be lowered to suit (18 degrees) but after awhile especially during the night it automatically resets to 23 degrees .
That said, we had a very very pleasant stay and the Skybar has spectacular views of the city. It’s fantastic for getting around as right from the front door there ar bikes to hire, metro station over the road and a fully manned Taxi rank 100 meters away
