Hey Ronin might be a little late as i saw your in London by your instagram? anyways here's some of Russia and Finland pics first then ill try to type what i know
So yea, we were in St. Petersburg for 3 days we stayed at the "Sokos" hotel which is a finnish chain i believe but it felt very much like any hotel you would stay at in a north american city, it was actually very nice
We were essentially 2 blocks off the water front, everything is seemingly based around the main canals and most places you can walk to. We didnt get out very far from the core of the city but most of the major attractions are all there, Peter/Paul Catherdral, summer and winter palace, etc.
I'd say a canal cruise is a must, you see a tonne iin a short amount of time, the guides we had were very good and it was quite cheap
The metro is great for getting around and easy enough to use, although in Russia NOTHING is in english outside of menu's at restuarants so sometimes its challenging if you dont know what your looking for. The metro is also completely fucked how deep it is lol, picture the granville street escalator and quadruple the length and double the steepness lol
The war museum pictured above [i forget the name, i beleive it's suppose to be an "artillery museum" but it has litterally any war machine ever created is in a hugeeeeee palace type building, we were in there for like 3-4 hours and that was walking fast
to understand the scope of this place they had a Kilishnekov [sp] exhibit that probably displayed 250-300 AK47's in various configurations over like 6000 sq feet? lol id say if you have any interested in weaponry, Russian war history this is a must see, it's a very cool place
Peter and paul catherdral is essentially a full park where you buy seperate ticket punches depending on what you want to see in the park, whether its the cathedral, the jail cells, etc. i think there are 5 different attractions there
on the east side of the main canal where the city hall type building is is where most of the resturants/shopping etc are all, great for people watching
there are also many parks strewn throughout the city where they serve beer and food outside, we took a cruise from finland that goes through 8 locks into vyborg, which is a coastal town 2 hours outside of St.petersburg so we bussed in from there which felt pretty much like all the crazy highway/dash cam videos you see around lol
ahh i cant really give much more for sights/directions, the water front has a bunch of boats/stalls for food and beers and i think there was even some sort of hooker party boat there as well lol, if you have any other questions i can try to answer them
