What an amazing opportunity to see an underwater archeological park from a cool submarine like boat. The crew was phenomenal! A must-see when you visit Napoli! Come and discover one of the must unique subaquatic wonders of the world.
Helpful, English-speaking staff. EXTREMELY clean interior of sub, completely cooled by AC on a very hot, humid day. Great seat placement with large windows. Get there early to find proper parking.
We just took a trip with NemoSub and it was simply fantastic. The organization was impeccable, the staff was incredibly professional, yet human and passionate. The experience was truly amazing: it truly felt like a journey back in time, a perfect blend of sea, history, and authentic emotions.
A beautiful and evocative experience. The staff were very kind and friendly. They explained everything in a simple and concise way. The evening was very evocative, even though they recommended doing it in the afternoon. Anyway, I'd definitely do it again. Thank you so much.
