The Aspire Lounge by Servisair is accessible via Priority Pass and is located near Gates 27 and 28 in the Schengen region. If you’re flying to a non-Schengen destination, you can still access this lounge, but you’ll need to leave a little bit of time to clear immigration to get to your flight.
The lounge is located on the second floor of the terminal, along with a restaurant and the Helsinki airport Book Swap, where you can take and/or leave a book.
The lounge isn’t particularly large, but it also wasn’t very crowded. There were some interesting seating options like hanging chairs and tiny wall cubbies.
There was a small island with drinks and food options, but the options weren’t particularly good. There was a hot soup available as well as karelian pasties, but the pasties were pretty cold and bad and not representative of what they can taste like. Otherwise, there was a meager alcoholic drink selection and things like cookies and pastries.
Overall, the lounge was fine to stop by in and had some interesting furniture, but assuming you have access to the non-Schengen area, the Almost@Home Lounge is also accessible via Priority Pass and offers better amenities.
