All italian ports are interesting. Genoa is one of them. But due to shortage of time, we could only do the aquarium and walked around for half an hour.
A very interesting port because from here you can visit Sorento (amalfi drive) or Capri. I have been here twice so i have seen both. This is one of the best ports to go to as the choices are fantastic.
Been here a few times. A very good port to go to as there is a lot to do at barcelona. The Ramblas, the Gaudi church etc. Must take the Hop in hop out bus if you have the time. Red color is better.
