We had Leena as our guide for a 2.5 day tour of St Petersburg in July 2019. She is probably the best guide we have used anywhere. I am not going to tell you all the things we did; just read all the other reviews and they are not exaggerating, Red Sun tours is that good.
I will tell you that one day of our tour was on Russian Navy day. Scores of naval vessels paraded through the river Neva viewed by President Putin and a million of his closest St Petersburg friends. Leena and her driver Igor, not only got us to all of our planned activities without much delay, but also we were able to view some of the naval action as well. Leena makes you feel like part of the family and knows any thing you need to know about Russian history, culture and daily life. BTW, her English is flawless.
