 First off I have no idea how this hotel is 4 stars it felt more 2 3 I was extremely disappointed in my room as you can hear everything It sounded like I was sleeping outside because the windows and walls are poorly insulated for sound You can hear everyone checking in if you are in the 100 s for rooms I could only sleep with my noise canceling headphones and music playing due to the terrible insulation If you get stuck with the 100 s rooms you are doomed I kept hearing how there werent many rooms available so I avoided changing my rooms and going through more stress The traffic is loud and the staff can be aloof I asked for help with something and the girl at the front desk was cold and brushed me off I really should have changed hotels and regret booking Catalonia Barcelona 505 hotel last minute 
 The cleaning service was nice
