I had a very comfortable stay. If I ever visit Helsinki again, I would definitely stay here.
(Good)
The hotel staffs were extremely courteous and attentive from check-in through check-out.
This hotel includes complimentary breakfast, afternoon tea starting at 3 PM, and dinner. Considering the cost of meals in Finland, this is a huge plus. Although my hotel checkout was early in the morning before breakfast began, they kindly provided a simple takeout breakfast at no charge.
The hotel's interior was beautiful. It's also fascinating that some sections, tucked away in less noticeable areas, still retain original prison cells.
The tram station was nearby, making it convenient to get into the city center.
(Bad)
The meal menu was basically the same every day (with some variations), so I got a little bored. Since it's free, I can't complain, and they don't need to change everything daily, but I think it would be better if they varied the menu options a bit more.
