The main reason why we picked citizenM to stay in Rotterdam was its convenient location in the city center. But it turned out that's not its only asset! You now know Rotterdam is all about modern architecture and citizenM fits perfectly into that. You can check-in by yourself and in your room you get to pilot everything with an iPad (from temperature, to lighting, to music). I advice you pick a room with view on the harbor on the upper level. You'll see the room is small but very cosy! And you get all of this for a decent price.
