We also visited a great art space in St. Petersburg called Loft Project Etagi. There it felt a little bit like Berlin and we were surprised that they have this space in the middle of the city centre. There was also a small cinema with films in original language, just when we were there, they were showing the great German movie "Victoria"
Hans and Paul even made new friends.
We also visited the main station of St. Petersburg, from there you can reach Moscow in 4 hours. We really liked the picture on the wall with all the destinations, there was Berlin on it :)
Here is a "making of" photo :)
