Reporting back after a short 1 night stay.
This was a great use of a FNA. Excellent hard product, staff were all friendly in a Finnish way, nice upgrade to a Sky Attic Studio. Breakfast is not included for elites but they offer it 1/2 off (so 18 euros). Breakfast was worth the cost. Limited selection but very high quality (just skip the bland omelettes they push on you when you walk in). Great location in the center of everything. My only complaint was the room scent was overwhelming, I had to cover up the diffuser with a towel to tamp down the smell (which was otherwise lovely). I will definitely stay here again.
Comparing this to the F6 and the Lapland: I really like the F6 and it's my usual go to. Quality wise the F6 is a slight notch below the St. George but given the usual $100+/night price difference, the F6 is a great option. The Lapland is also a notch below the St. George. I had a bad experience at the Lapland in Tampere, so even though I liked the Boulevardi location in Helsinki, I'll probably avoid them in the future.
Here is a current print out of the elite benefits and limitations:
