Otherworldly place!
We spent so much time trying out all the cool things and checking the fittings inside the submarine, taking photos, and pretending we're on a mission (we are both 32) and just marveling at this fantastic vessel.
It's a bit chilly at night in winter so bring some extra layers. The submarine is really cosy, clean, and stylish inside, it's got everything you need for a short stay.
We enjoyed it so very much, thank you Keith and Jen!
