HEL does not have one but two Aspire lounges.
The old one is near gate 27, as reported
here by @
Romanianflyer. The most recent one is near gate 13 (our AF flight has departed from gate 19).
AF/KL eligible flyers can access both lounges. Based on the report quoted above, food offer seems to be the same between the two lounges (don't expect too much), but the most recent lounge may feel more spacious. There is different type of spaces where to sit and it was not crowded for our Sunday evening flight. No shower in the lounge.
