Well... long story short:
I am working in Estonia, north of the EU. A nice flat and small country full of forests and nice people. I was having beers in Tallinn, the capital, with some friends... long night... night? here barely gets dark only on this part of the year... so early in the morning (or late at night) we happened to go near the harbour. I have never been to Finland or Helsinki. We should go, is only 2 hours Ferry and 20€. Do you have your Covid Passport? yes, in my phone.
So... why not?
20€ and and while later we were on the boat drinking and laughing to Helsinki.
Nice city, nice country, expensive beer. and just walking we happen to go to the door of a guitar shop.
