After a peaceful night and thanks to my Russian friend’s help with the Metro card I managed to reach the city center and walked to the Eremitage.
The Eremitage does not need any comment or rating. Its reputation is known all over the world. Just one word: after Peterhof the day before here was another indescribable collection of beauty, history and fine arts.

So much to see, so little time.
