We stayed at the beautiful castle hotel that's connected to the spa hotel via a tunnel. There are 2 saunas for ladies (only 1 for the men), a steam room that was so warm I could not stay for more than a few seconds because it was too difficult to breathe in there, 2 hot tubs, and a small pool. The river view from the third floor was lovely and the small balcony could fit a chair so I could sit and read. Across the street, there's a small museum. Restaurants and shopping are all within a 5 minute walking distance.
Breakfast was better than the 4 and 5 star hotels in Heksinki with a delicious spread of fruit salad, fresh whole fruits, porridge, cheese, meat, breads, jams, sausages, eggs, pastries, salad, coffee, tea, and milk. We had dinner there once and it was fine.
There are some bikes available for rent for 7 Euros a day and it's a great way to explore town and exercise at the same time. It's free if you take the bike out for only an hour or so.
Our bed was made of two twin beds put together with medium firm pillows. The soft pillows were in the closet and you could request for firm pillows. We had a small desk and chair that was adequate for a laptop. There was also a winged chair and a telephone chair.
They had a very cute kid's playroom with a castle and slide, dress-up clothes, train tracks, and duplos Legos.
