It turned out I guessed it. NEXT RIVOLI JARDIN is located on a quiet street a hundred meters from the central boulevard and within walking distance of all the main sights of Helsinki.
Pros.
Homely, warm, bourgeois atmosphere. But without familiarity.
Comfortable bed.

Awesome, fantastic breakfast.
Normal internet. Everywhere. (For some special one you have to pay extra. But I had enough free. )
Russian channel on TV.
Shop 24 hours nearby.
Loyal attitude to smoking.

Minuses.
Little. Very limited selection of drinks at the reception bar.
Too delicious breakfast. You get fat and walk with difficulty.
