We thoroughly enjoyed our stay at Hotel Arthur. While this property is older, everything we saw was clean and well maintained. The room was smaller, but big enough for the two of us. It was very clean and the beds were comfortable. The breakfast buffet was very good, with options familiar to Europeans, Brits and North Americans. The Karelian pastries with egg butter were a fantastic find. And the location is ideal.
If you are here to see Helsinki, on your own dime, this is an excellent place to stay. Clean room, comfy beds and a delicious breakfast that will keep you going as you investigate the city until mid-afternoon.
