Honeymoon in Barcelona - Recommendations?

Hello,
we will move to BCN in Protected content . I love this city and will spend my honeymoon as well in BCN.
Does anyone have a REALLY special idea where to spend 5 days in BCN. the place needs to be fantastic! I found a few hotels on Protected content - these places look stunning, but I am sure there must be more, no?
all suggestions a greatly appreciated! peace and love!
