 I stayed this hotel at the end of CY2015 As you know a fireworks performed around Spain square But I could not enjoy this fireworks due to early close of roof in this hotel I can imagine easily this hotel will be more fascinated if roof will be opened till midnight only year end day 
 This hotel is located in very comvenient place be able to take a train and bus easily At the roof of this hotel you can enjoy nice view we could see almost all famous landmark in Barcelona
