Hey, I am really sorry for the delay, hope the message is going find you before your trip!:)
Well, everything is small on that boat, but at the same time well done. Each floor has at least two bathrooms with toilets, so you dont have to wait so much. The breakfast is quiet nice, especially after a long night:)!! But I would say the best thing is the location, is 5 minutes from the Central Station by taxi, but later you will find your way easily on foot as well! Quiet close to everything! We took the underground just to get the experiance! Have fun, and again sorry that I replied so late!! Take Care and have a nice time!!
