We booked Polina to tour us around Peter and Paul Fortress. We were a group of 6 adults and 3 children under 12 years old. Here rate was very reasonable - the most reasonable of the 4 proposals we received. She was knowledgeable of Peter and Paul Fortress. As she took us around the prison cells, she allowed us to experience what it would be like to be in solitary confinement, to be inside a cell, and she told us stories of particular inhabitants and what happened to them or how they died. She made the tour interesting and showed us the tombs of the czars, including the Romanovs. At the end, we had told her where we were having a meal after (Koryushka) and she surprised us as she arranged for an electric car from the restaurant to pick us up. Would book her again!
