People say St. Petersburg looks like Stockholm in some way + the same climate. I have never been to Stockholm (but I would like, of course) because it was too far from me 😃 - I usually spent my time in South and Southeast Asia last years before covid. + I need visa - and visas are boring. There are (were?) direct ferries from St.P to Stockholm.
Not many regulations. Most people don't wear masks in shops and public transportation although they officially must. At the same time, the government is trying to make people use QR-codes (as a proof of being vaccinated) and nobody likes it. I think the government will give up trying.
