Artem Goutsoul: Great coffee (esp. dark roasts), exceptional service even when crowded and a great view to Aleksanterinkatu. After trying one of their coffees you can actually buy a pack!
Artem Goutsoul: Great view towards the Opera and the sea. Nice breakfast, free wifi. Annoyingly you have to re-login every day (username: Thon, password: guest). Umbrella included with the room!
