Just returned from from 7 night western med cruise from Barcelona. We have previously cruised with NCL 3 times.
Embarkation slick and easy, taxi from Barcelona cathedral costing 13 euros. Not worth queing for the the 3 euro bus, tpoo hot, too busy.
The ship is showing signs of age and appears tired in places. The layout is easy to navigate however there was a lack of public space around the atrium. The bars were good, in particular the Whisky bar, great staff and some good music. Try out the quiet zone sun deck on deck 18. Great beds and some space to relax.
