I spent 5 great days in Saint Petersburg this week!
This was my first visa and I was worried about the needed paperwork (insurance, hosting certificate, ...), and then the registration after arriving. Getting the visa was not easy as you need to go to the embassy on Monday, Tuesday or Thursday between 9:00 and 12:00 and spend some time there (queuing 3 times...). Then you can chose to get the visa as soon as it is ready (the same day) for 70 euros, or wait 7 days before picking it up and only pay 35 euros...
At the airport I was welcomed with huge queues for passport checks (I think I spent about 30 minutes there) and then by Ирина which was better :)
Apart from usual buildings and museums (I admit I haven't visited some major ones), I visited a great bar/club on the first evening, which I enjoyed even if I had not slept the night before (We went there again the next day and it was much better :) ).
I can now pronounce most letters (not all) and often understand the word when it sounds like French or English (or other, like CYШИ for sushi) but reading letter by letter is so slow... And I can't manage to read anything hand written :(
I hope I'll have the opportunity to go there again!
