I arrived really early after an intercontinental flight and was pleasantly surprised at front desk when a room was already available at 7.30 am. I was even offered a possibility to have breakfast already when checking in (besides with the normal next day), with a fee of 14 eur which I declined. Receptionist spent some time explaining what the attached shopping mall had to offer: there is a spa, a bowling areena among others. Receptionist was very helpful, cheerful and service oriented (not very typical for Finns).
Our twin room at 9th floor was really spacious and very clean. Bed a bit too soft to my taste, I would have liked a firm mattress. Free wifi and parking. Breakfast typical for this Sokos hotel chain with an unexpected extra: chocolate fountain! Never seen that in a Finnish hotel, at breakfast. Besides chocolate fountain, the breakfast consists of variety of bread, cheese, sausages, eggs, bacon, porridge, cereals, jogurt, apple and orange juice, coffee&tea. So I think everybody's taste is being served.
Hotel is adjoining Jumbo Mall, so lots of shopping opportunities. Restaurant Amarillo and Sir Eino give you entertainment until late night. Location wise this is not exactly an airport hotel, because there are similar hotels even closer to the airport and they do not offer shuttle to Flamingo but taxi is not very costly either (about 14 euros/10 minutes drive). I think there is public transportation if you want to check out Helsinki.
Extra towel set costs 4 euros (I think you might need them if you visited the spa).
We did not face problems with the elevators. Our bathroom bide shower was leaking water on the floor, and this we mentioned while checking out. The receptionist was (again) very service oriented, apologized and cared about our socks getting wet. She promised that it would be fixed before next guests arrived.
This hotel is just what one can expect from a Finnish 4 star hotel. I can recommend i t to my friends with no doubts.
