Hello Liza,
Greetings from Saint-Petersburg! I`m having the time of my life! I have been to Saint-Petersburg for three weeks.
I`ve seen a lot of attraction and been in Nevsky Prospect. My family and I have been in Hermitage. Together we`ve gone souvenir shopping, seen famous landmarks. Sain-Petersburg is amazing!
See you in three days. Take care!
Love, Sergei.
