Not sure about bars these days but Valetta used to be a cracking night ashore.Not sure about Valletta mind. Some lovely churches but not that many bars / restaurants.
Off to Barcelona this week. Haven’t been for about 10 years, so any suggested would be appreciated.
Would concur with Prague & Rome. Both easy to walk around.
Düsseldorf is nice but full of German hen & stag do’s copying British stag do’s.
Its one of the best harbours in the world and a very pretty city
