We stayed one night at the SS Rotterdam to experience the ship turned hotel. As you step onto the ship you're transported to the golden years of cruising with its art deco furniture, nautical uniforms of the front desk staff, and the golden accents in the lobby.
The Room: the rooms are former cruise cabins refurbished as guest rooms. The rooms are very retro with 60's type furnishings but very comfortable. We stayed in a harbor view room. The view is nice but I recommend the port side of the ship which has a lovely city view of the modern architecture of the city.
The Location: Although not centrally located, there are many ways to get to the hotel. If coming from Rotterdam Centraal Station, take a metro and then a bus to get to the hotel (the hotel has also shuttle service from the metro to the hotel). We decided to take a taxi from the central station. The taxi from the station to the hotel was around 25 Euros. There is ample parking if you're coming by car (15 Euros per day). Another way to get around is by water taxi. Wish we could have done that, but we were too short on time, it's an affordable way to catch great views of the city!
