This is an historical hotel, during the WWII there were some headquarters here. It is also one of the highest buildings in the centre of Helsinki. On the top floor there is a small pub and on the ground floor there is one of my favourite pubs of Helsinki, O'Malley's, Helsinki’s first Irish pub.
I have never seen the rooms, but the rooms have: Air conditioning Television Satellite television In-house movie Radio Direct dial phone Mini bar Hairdryer Trouser press Automatic wake-up call
The hotel has a tower offering unique views over Helsinki. There's a nice small bar in the tower. You should check the bar's toilet because the best views you are getting is from there. :-)
