I chose the Hotel Arthur mainly because it was a rather cheap hotel in contrast to others nearby and because of the fact that it is located close to the main railway station of Helsinki, Finland. When I arrived I was nevertheless quite surprised: it is rather old-fashioned, partially in a bad state and the elevator comes from a different century. And it is operated by the local Young Men’s Christian Association (YMCA). If you need something more beautiful book somewhere else, if you just need a cheap bed for the night this is your place.
I had the feeling that only some parts of the hotel are rather old; maybe you’re lucky and can get a freshly renovated room. The location of the hotel is perfect; apart from being only ten minutes on foot from the main railway station you have the tramway stops Kaisaniemenkatu and Kaisaniemenpuisto directly next to the hotel. It is only a very short walk to the Senaatintori square and the harbor; the hipster quarter Kallio is in the direct neighborhood. And if you need a good (but costly) drink: check out the Flying Dutch, a bar on a ship anchoring just 500 meters afar.
