I arrived at 7am and was charged 20 euros for early check-in as the usual check-in time is 4pm. The front desk is manned 24 hrs and the staff are on-the-ball.
The hotel's location is superb; Just a stone's throw to Kauppatori market, senate square, Helsinki Cathedral and Uspsenski Cathedral. It is located right beside the university, right beside an underground passage to casino, train station and food hall. It is also right next to a recycling shop where you can shop for 2nd hand stuff. There is a tram stop right outside the hotel so it helps if you are feeling tired and wanted to walk lesser. The down side is of course you can hear the trams travelling from the hotel room (it's quite muffled though audible). The worst part is the sound proofing because you can hear other rooms' flushing and when people walked past.
There is no mini fridge nor mini bar in the room.
Breakfast wise, there was a spread but it was not as varied as I expected it to be after reading the reviews. The breakfast was mainly assorted bread & jam, pickled vegetables, assorted cheese, chicken ham, oat porridge, overnight cereal, assorted cereal, rye rice pastry, scrambled eggs, 6 min egg, bacon, rosti (hashbrown), beetroot balls, baked beans, tomato with egg, assorted juice.
The floor has some sand which I called for room service to clean the floor but the sand is still there.
Room service is fantastic; they would change towels everyday unless you put do not disturb.
