Thank you very much Irina for a wonderful two days tour of St. Petersburg. Irina is extremely energetic and knowledgeable about the history, arts and architecures of the city. Her English is impeccable. In addition she is flexible and always willing to accomodate our needs. She was able to help us navigate / avoid the long lines at the popular museum doors (minimum wait time). We would gladly have her as our tour guide again and we highly recommend her service to anyone.
